Mass Formula:
From: | To: |
The weight to mass conversion calculates an object's mass from its weight using the gravitational acceleration. Weight is a force measured in Newtons, while mass is a fundamental property measured in kilograms.
The calculator uses the formula:
Where:
Explanation: This formula converts the force of weight to mass by dividing by the gravitational acceleration. On Earth, standard gravity is approximately 9.8 m/s².
Details: Understanding the difference between weight and mass is fundamental in physics. Mass is constant regardless of location, while weight changes with gravitational field strength.
Tips: Enter weight in Newtons and gravitational acceleration in m/s². For Earth calculations, use the default value of 9.8 m/s². All values must be positive numbers.
Q1: What's the difference between weight and mass?
A: Mass is the amount of matter in an object (constant), while weight is the force exerted on that mass by gravity (varies with location).
Q2: Why is Earth's gravity 9.8 m/s²?
A: This is the average acceleration due to gravity at Earth's surface, though it varies slightly by location (9.78-9.83 m/s²).
Q3: How would my weight change on other planets?
A: Your mass would stay the same, but your weight would change proportionally to the gravitational acceleration of that planet.
Q4: Can I use this calculator for objects in free fall?
A: No, this calculator assumes the object is at rest relative to the gravitational field being measured.
Q5: What if I know mass and want to find weight?
A: Simply rearrange the formula: Weight = Mass × g.
