For example, your waist is 80 centimeters. According to formula 80-5 = 75 kg. Of course, this figure is not entirely accurate, but it is enough to determine the need to diet.

to speculate on the wrist

This method also is elementary, but unfortunately still less accurate than the volume waist experiment. Still, if you're worried about how to find the balance without the weight quickly, then you can help your wrist and growth. By the way, it does not even need a tape measure, which makes this option even more convenient calculation.

So, hold your wrist so that the thumb and index finger is free to join. If this trick succeeded without difficulty, then you treat astenik - people slim build. In this case, the formula for calculating the following: (height - 100) - (height x 0.1) = your approximate weight. For example, you could connect the fingers to the wrist and your height is 168 centimeters. Calculate: (168 - 100) - (168 x 0.1) = 51.2 kg. But this formula only works for this body type, and only in the absence of obesity apparent problems.

People who are not free to embrace your wrist, it is necessary to calculate the weight of a little different (height - 100) + (height x 0.1) = your approximate weight. In the example, this is: (168 - 100) + (168 x 0.1) = 84.8 kg. As you can see, the difference is palpable, so it is important to approach the measurement of wrist honest and remember that the ring finger should be free.

Archimedes

This method is the most accurate of all the options on how to find out without weights his weight. But it is quite difficult and is suitable not for everyone. All the complexity is that it will take some effort and find the appropriate tools.

Thus, according to Archimedes' principle, any body that is submerged in the liquid, it will push out as much as the volume in the body itself. Translated into plain language - put yourself in a full bath or a barrel, collect the water, which in this case will result, and you will know your weight. Of course, for an adult, this method is hardly suitable, but if you are tormented by the question, how do you know the child's weight without weights, then Archimedes to help you.

Fill the baby bath to the brim, and place the baby. Part of the water necessarily will result. It remains only to find out its volume. To do this, there are two ways. Origin - collect liquid liter banks (conditionally taking 1 liter per 1 kilogram). The second - on the contrary, to fill the tub to the brim, considering how many liters of need.

Teeter

You can find many more ways on how to find out without weights his weight. But the most fun are ordinary children's swings on which you want to ride together.
