Ponderal index

The ponderal index is somewhat comparable to Body mass index, but gives a more fair comparison between individuals of different stature.

Instructions:
1. Measure weight and height and enter values.

Background

Ponderal index is calculated as weight divided by height raised to the power of 3.

Ponderal index = kg / (m x m x m)

Quoting Carl:
Hi
Thank you for providing the Ponderal index calculator, just a quick comment to say that the units in the weight should be kg (kg with a small case "k" and not Kg).

Technically, the units used for weight should be Newtons (N). The quantity should be mass instead of weight if we want to use kilograms.

Do you have plans for making a ponderal index calculator for children shorter than 4'11"? Or if this calculator doesn't apply to children at all, then one for children specifically?

Paul -> yes, that is the formula. We will very soon update this calculator with the option to use imperial units. (Why couldn't we not just all agree to use SI-units ;-)

Formula: like density: mass divided by volume (height x height x height)

The Index is for international units. For imperial units and other local units like stones and handwidth you need to translate them.

Try searching "pondural" instead of "ponderal." I don't know why this is, but there seems to be a spelling change between the literature and lay use.

Hello Morten
I want to know why there are no article references on the topic, ponderal index?
