BMI Calculator for Male and Female: Does Gender Matter?
Many users search for a specific BMI calculator female or BMI calculator male to see if the results differ by gender. Officially, the standard formula to calculate BMI gender wise remains the same for both adult men and women.
However, how the body carries fat can be different. A BMI calculator Female kg assessment might show the same number as a male, but women naturally tend to have a higher percentage of body fat than men at the same BMI score. Therefore, while using a BMI calculator for gender tracking is a great starting point, muscle mass and body composition should also be kept in mind.
