Ponderal Index

英语百科

Corpulence index

The Corpulence Index (CI) or Ponderal Index (PI) is a measure of leanness of a person calculated as a relationship between mass and height. It was first proposed in 1921 as the "Corpulence Index" by Rohrer and hence also known as Rohrer's Index. It is similar to the body mass index, but the mass is normalized with the third power of body height rather than the second power.
