Long before birth of the kid of parents interests that the baby feels that he hears which of parents will resemble, what he growth and how many weighs. Such interest is caused not only by love of parents, but also concern on health of the baby whether correctly it develops. To learn the weight of the kid in mother's womb, it is possible to address statistical data or the expert in local policlinic, and it is possible to calculate approximate values in independently simple way.
It is required to you
- - centimetric tape;
- - sheet of paper and handle;
- - calculator.
Instruction
1. Learn uterus bottom height from the doctor under whose observation you are. This size is distance from the upper edge of a lonny joint to the bottom of a uterus (its top part). Record this size, for calculations call it Vm.
2. Take necessary measurements. Measure by a centimetric tape a stomach circle at the level of a waist. Record the received result, designate the received size as Ozh value. Measure a wrist circle on a non-working hand. If the received size less than 16 cm, then coefficient And it is equal 12 if more than 16 cm – the coefficient And accepts value 11.
3. For the accuracy of required result make calculation for three formulas, and calculate an arithmetic average value. The first value for calculation: increase the size Vm by Ozh value, record the received result as size P1. Calculate value by the second formula: divide the sum of Vm and Ozh into 4 and increase by 100, write down the received value as P2. For calculation in the third way (P3 value) subtract value of coefficient from the size Vm And, increase the received number by 155.
4. Calculate an arithmetic average value: put values of sizes P1, P2 and P3, and divide result of addition into 3. It will also be the estimated weight of a fruit at the moment. The error can make about 200 grams.
