Determining your weight without a scale can be useful in various situations, such as when traveling or when a scale is not readily available. There are several methods you can employ to estimate your weight with reasonable accuracy.
One common method is to use a measuring tape to measure your height and waist circumference. You can then use a formula to estimate your weight based on these measurements. For example, the Devine formula for men is:
Weight (kg) = 56.2 + (1.41 x height (cm)) + (2.09 x waist circumference (cm)) – (0.18 x age (years))
And for women:
Weight (kg) = 43.5 + (1.13 x height (cm)) + (2.86 x waist circumference (cm)) – (0.16 x age (years))
Another method involves using a chair and a sturdy object, such as a backpack or a bag filled with books. Sit on the chair and place the object on your lap. Grip the object with both hands and lift it overhead while standing up. Repeat this process several times and count the number of repetitions you can do before reaching exhaustion. You can then use a table or chart that correlates the number of repetitions to your approximate weight.
These methods provide a reasonable estimation of your weight and can be particularly helpful when a scale is not accessible. However, it’s important to note that they are not as accurate as using a scale and may vary depending on factors such as body composition and fitness level.
