Kg to N Conversion Formula:
From: | To: |
The kg to N conversion calculates the force (in newtons) exerted by a mass (in kilograms) under the influence of gravity. It's based on Newton's second law of motion: Force = mass × acceleration.
The calculator uses the formula:
Where:
Explanation: The formula converts a mass measurement to the equivalent force it would exert under standard Earth gravity.
Details: This conversion is essential in physics, engineering, and many practical applications where you need to know the force exerted by a mass, such as in structural design, mechanical systems, and weight measurements.
Tips: Enter the mass in kilograms and the gravitational acceleration (default is Earth's gravity at 9.81 m/s²). All values must be positive numbers.
Q1: Why is gravity 9.81 m/s²?
A: This is the average acceleration due to gravity at Earth's surface. It varies slightly by location (9.78-9.83 m/s²).
Q2: How would this change on the Moon?
A: Use Moon's gravity (1.62 m/s²) instead of Earth's. A 1 kg mass would exert about 1.62 N on the Moon.
Q3: Is weight the same as mass?
A: No, mass is constant (kg), while weight is the force (N) that mass exerts under gravity.
Q4: Can I use this for other units?
A: You must use kilograms for mass to get newtons. For pounds, you'd get pound-force (lbf).
Q5: What's the difference between N and kg·m/s²?
A: They're equivalent units - 1 N = 1 kg·m/s². Newton is the SI derived unit for force.
