N'ihe banyere calculator a
This calculator estimates body fat percentage using the U.S. Navy circumference method, which needs only a tape measure. It feeds your height, neck and waist measurements — plus hip for women — into the Navy formula, which uses the ratio between these circumferences to estimate how much of your body is fat. Enter your weight too and it also splits that into fat mass and lean body mass.
For example, a man 175 cm tall with a 38 cm neck and an 85 cm waist comes out at roughly 17% body fat, which sits in the fitness range. Measuring accurately matters: keep the tape snug but not compressing the skin, take the waist at the navel and the neck just below the larynx.
Use it as a free, at-home alternative to calipers or a DEXA scan for tracking fat loss or muscle gain over weeks and months. It is an estimate, typically within a few percent of a lab measurement, so focus on the trend between measurements rather than any single reading.
