It is necessary to weigh your suitcase before leaving for your trip because there is a weight limit and you may need to pay extra in the airport. Finding a scale just to weigh your suitcase is difficult especially when you are traveling. However, there are other alternatives to determine the weight of your suitcase without using any scale.
A practical method is using a digital bathroom scale to weigh your luggage. First, you need to weigh yourself by standing on the scale. Then, you need to hold your suitcase and weigh yourself together. After that, subtract the weight without your suitcase from the weight with your suitcase to determine the weight of your luggage.
Alternatively, you can use a luggage strap with a built-in scale. These straps are designed specifically for weighing luggage and are easy to use. Simply attach the strap to your suitcase and lift it off the ground. The strap will display the weight of your luggage on a digital display.
The Bathroom Scale Hack
This method is the simplest and most accurate way to weigh your suitcase without scales. Here’s how it works:
1. Step on the bathroom scale and record your weight.
2. Holding the suitcase steady, step onto the bathroom scale again. The difference between the two weights is the weight of your suitcase.
For example, if you weigh 150 pounds without the suitcase and 175 pounds with the suitcase, the weight of your suitcase is 25 pounds.
Here’s a table to illustrate the process:
| Step | Weight (pounds) |
|---|---|
| Without suitcase | 150 |
| With suitcase | 175 |
In this example, the weight of the suitcase is 25 pounds (175 – 150).
The Laundry Bag Method
This method involves using a laundry bag and a sturdy suitcase that can withstand the weight. Here’s a step-by-step guide:
1. Fill the Laundry Bag with Items:
Pack the laundry bag with the items you want to weigh. It’s important to include everything that will go inside your suitcase, including clothes, shoes, toiletries, and electronics.
2. Elevate the Suitcase and Hang the Laundry Bag:
Place the suitcase on a sturdy surface, such as a table or bed. Thread a strong string or rope through the handles of the laundry bag. Carefully lift the laundry bag and suspend it from the suitcase handles.
3. Push Down on the Suitcase:
Use your body weight to push down on the suitcase gently. Pull up on the laundry bag simultaneously. The suitcase will rise as the weight of the bag pulls it upward.
4. Adjust the Tension:
Gradually adjust the tension on the string or rope until the suitcase balances evenly. This point indicates that the weight of the laundry bag is equal to the weight of the suitcase and its contents.
5. Determine the Weight:
To determine the weight, use a bathroom scale or a kitchen scale. Place the laundry bag on the scale and record the weight. This is the approximate weight of your suitcase.
Note: This method provides an approximate weight and may not be as accurate as using a luggage scale. However, it’s a convenient way to estimate the weight of your suitcase without having to purchase or borrow a scale.
The String and Ruler Technique
The string and ruler technique is a great way to weigh your suitcase without scales. It’s a relatively simple process, but it does require some precision.
Here’s what you’ll need:
- A string or rope
- A ruler
- A calculator
Instructions:
1. Tie the string around the suitcase’s handle.
2. Lift the suitcase by the string and wrap the string around the ruler.
3. Mark the point where the string meets the ruler.
4. Measure the length of the string from the mark to the end of the ruler.
5. Multiply the length of the string by the weight per inch of the string. This will give you the weight of your suitcase.
Calculating the Weight Per Inch of the String
The weight per inch of the string will vary depending on the type of string you’re using. You can find the weight per inch of the string by using a scale.
Here’s how to do it:
1. Tie one end of the string to the scale.
2. Hang a weight from the other end of the string.
3. Record the weight on the scale.
4. Divide the weight by the length of the string. This will give you the weight per inch of the string.
Once you know the weight per inch of the string, you can use the following formula to calculate the weight of your suitcase:
“`
Weight of suitcase = Length of string * Weight per inch of string
“`
For example, if you have a suitcase that is 24 inches long and you’re using a string that weighs 0.1 ounces per inch, the weight of your suitcase would be 2.4 ounces.
The Online Calculator Option
If you’re looking for a quick and easy way to estimate the weight of your suitcase without using scales, there are several online calculators that can help. These calculators typically require you to enter the dimensions of your suitcase, along with an estimate of how full it is. Based on this information, the calculator will provide you with an estimated weight.
Steps to Use an Online Suitcase Weight Calculator:
- Measure the height, width, and depth of your suitcase in inches or centimeters.
- Estimate how full your suitcase is, using a percentage (e.g., 50%, 75%).
- Enter these values into the online calculator.
- The calculator will provide you with an estimated weight in pounds or kilograms.
Here is a table summarizing the steps involved in using an online suitcase weight calculator:
| Step | Description |
|---|---|
| 1 | Measure the height, width, and depth of your suitcase. |
| 2 | Estimate how full your suitcase is. |
| 3 | Enter these values into the online calculator. |

The Hydraulic Lift Principle
The hydraulic lift principle is based on Pascal’s law, which states that pressure applied to a fluid in a closed container is transmitted equally to every part of the fluid and to the walls of the container. In a hydraulic lift, this principle is used to create a mechanical advantage, allowing a small force to lift a much heavier load.
How It Works
A hydraulic lift consists of two cylinders of different diameters connected by a pipe. The smaller cylinder is filled with a fluid, and a piston is inserted into it. When a force is applied to the piston, the fluid pressure increases. This pressure is transmitted to the larger cylinder, which has a larger piston. The larger piston experiences a greater force, which is used to lift the load.
Applications
Hydraulic lifts are used in a variety of applications, including:
- Automotive lifts
- Forklifts
- Cranes
- Elevators
Advantages
Hydraulic lifts offer several advantages over other types of lifting devices, including:
- Smooth and precise operation
- High mechanical advantage
- Compact size
- Low maintenance requirements
Disadvantages
Hydraulic lifts also have some disadvantages, including:
- Potential for leaks
- High cost
- Limited stroke length
Table: Comparison of Hydraulic Lifts to Other Lifting Devices
| Feature | Hydraulic Lift | Other Lifting Devices |
|:—|:—|:—|
| Mechanical advantage | High | Varies |
| Smoothness of operation | Smooth | Jerky |
| Compactness | Compact | Bulky |
| Maintenance requirements | Low | High |
| Cost | High | Low |
The Kitchen Balance Strategy
If you have a kitchen balance, you can use it to weigh your suitcase. Just follow these steps:
- Place the empty suitcase on the balance.
- Set the balance to zero.
- Start adding items to the suitcase.
- As you add items, the balance will display the weight of the suitcase and its contents.
- When you have finished packing, the balance will display the total weight of the suitcase.
Tips for Using the Kitchen Balance Strategy
- Make sure that the balance is accurate. You can do this by weighing a known weight, such as a bag of sugar.
- Weigh the suitcase on a flat, level surface.
- If the suitcase is too heavy for the balance, you can weigh it in two or more parts.
Weighing a Suitcase in Two or More Parts
If the suitcase is too heavy for the balance, you can weigh it in two or more parts. Just follow these steps:
- Divide the contents of the suitcase into two or more equal parts.
- Weigh each part on the balance.
- Add the weights of the parts together to get the total weight of the suitcase.
Example
Let’s say that you have a suitcase that weighs 50 pounds when it is empty. You pack the suitcase with clothes and other items, and the total weight of the suitcase is now 75 pounds. To weigh the suitcase using the kitchen balance strategy, follow these steps:
- Place the empty suitcase on the balance.
- Set the balance to zero.
- Start adding items to the suitcase.
- As you add items, the balance will display the weight of the suitcase and its contents.
- When you have finished packing, the balance will display the total weight of the suitcase: 75 pounds.
The Slippery Slope Approach
This method involves using a suitcase with wheels.
- Find a slippery surface: The surface should be smooth and have a slight incline. A tiled floor or a smooth driveway works well.
- Place the suitcase on the surface: Position the suitcase at the top of the incline.
- Let the suitcase slide: Release the suitcase and allow it to roll down the incline.
- Time the descent: Use a stopwatch or your phone to measure the time it takes for the suitcase to travel a certain distance (e.g., 20 meters).
- Measure the incline: Use a level or an inclinometer to measure the angle of the incline.
- Calculate the weight: The weight of the suitcase can be estimated using the following formula:
Weight = Time² * Gravity * Distance / (Sin(Incline Angle) * 2)
| Variable | Description |
|---|---|
| Time | Time taken for the suitcase to slide the distance (in seconds) |
| Gravity | Acceleration due to gravity (9.81 m/s²) |
| Distance | Distance traveled by the suitcase (in meters) |
| Incline Angle | Angle of the incline (in degrees) |
- Additional Considerations:
a. Ensure that the suitcase is not too heavy or too light, as this can affect the accuracy of the measurement.
b. If the incline angle is not precisely measured, it can introduce errors into the calculation.
c. The method assumes that the suitcase rolls with negligible resistance, which may not always be true, especially for uneven surfaces or suitcases with defective wheels.
