How do I calculate BMI manually?
Then, calculate BMI by dividing weight in pounds (lb) by height in inches (in) squared and multiplying by a conversion factor of 703. When using a handheld calculator, if your calculator has a square function, divide weight (lb) by height (in) squared, multiply by 703, and round to one decimal place.
How do you do BMI step by step?
To calculate your body mass index (BMI), start by measuring your height in meters and then squaring it. Then, divide your weight in kilograms by your height in meters squared to find your BMI. If you’re using imperial measurements, start by measuring your height in inches and then squaring it.

How is weight and mass calculated?
Difference between MASS and WEIGHT – YouTube
How do you convert weight to mass?
It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms. The Newton is the SI unit for weight, and 1 Newton equals 0.225 pounds.

Does BMI change as you age?
BMI changes substantially with age. After about 1 year of age, BMI-for-age begins to decline and it continues falling during the preschool years until it reaches a minimum around 4 to 6 years of age. After 4 to 6 years of age, BMI-for-age begins a gradual increase through adolescence and most of adulthood.
