What is {primary_keyword}?
The {primary_keyword} is a tool used by the United States Navy to assess a service member’s body composition. It calculates the Body Mass Index (BMI) based on weight and height, providing a quick health indicator. The {primary_keyword} helps determine fitness eligibility, readiness, and potential health risks.
Anyone in the Navy, including active duty, reserves, and cadets, should use the {primary_keyword}. It is also useful for civilian personnel who want to compare their measurements against military standards.
Common misconceptions about the {primary_keyword} include the belief that BMI directly measures body fat or that it accounts for muscle mass. In reality, BMI is a simple ratio and does not differentiate between muscle and fat.

Since height is entered in centimeters, the formula becomes:
BMI = weight ÷ (height/100)²

|---|---|---|---|
| weight | Body weight | kg | 30‑200 |
| height | Body height | cm | 100‑250 |
| BMI | Body Mass Index | kg/m² | 10‑50 |
