kg to Newtons Calculator

Mass to Weight Conversion

Convert between mass (kilograms) and weight (Newtons) using gravity values from different celestial bodies.

Calculator

From
kg
To
N
Formula:
Weight (N) = Mass (kg) × g
g = acceleration due to gravity

Mass vs Weight

Mass: Amount of matter in an object (constant everywhere)

Weight: Force of gravity on an object (varies by location)

Key Point:

Your mass stays the same on Earth and Moon, but your weight changes!
