How to Calculate Your Mass in Kilograms: A Step-by-Step Guide

Learn how to accurately calculate mass in kg using our simple formula based on weight and gravitational acceleration.

420 views

To calculate mass in kg, use the formula: mass = weight / gravitational acceleration. On Earth, the gravitational acceleration is approximately 9.81 m/s². For example, if you weigh 98.1 Newtons, then your mass would be calculated as 98.1 N / 9.81 m/s² = 10 kg. Ensure your weight is in Newtons and gravitational acceleration is in m/s² for this formula to work correctly.
