Ponderal Index Calculator Online



The formula for calculating Ponderal Index (PI) is

Ponderal Index (PI) (For Adult) =
Weight / Height 3
* 1000000

Ponderal Index (PI) (For Child) =
Weight / Height 3
* 100

Example of Calculations (For Adult):

Height: 170 cm

Weight: 43 kg

Ponderal Index (PI) (For Adult) =
43 / 170 3
* 1000000 = 8.75 (Your PI is too low. You are underweight.)

Example of Calculations (For Child):

Height: 23 cm

Weight: 12 g

Ponderal Index (PI) (For Child) =
12 / 23 3
* 100 = 0.099 (Low index value, small-for-date baby)
