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!
Features
