Weight Formula:
From: | To: |
Definition: This calculator computes the weight (force) based on mass and gravitational acceleration using Newton's second law.
Purpose: It helps students, engineers, and scientists convert between mass and weight for various applications.
The calculator uses the formula:
Where:
Explanation: Weight is the force exerted by a mass under gravitational acceleration. On Earth, standard gravity is 9.81 m/s².
Details: Proper weight measurement is crucial in engineering, physics, and everyday applications like material handling and structural design.
Tips: Enter the mass in kilograms and gravitational acceleration (default 9.81 m/s² for Earth). All values must be > 0.
Q1: What's the difference between mass and weight?
A: Mass is the amount of matter (constant), while weight is the force exerted by gravity on that mass (varies with gravity).
Q2: Why is Earth's gravity 9.81 m/s²?
A: This is the average gravitational acceleration at Earth's surface, varying slightly by location.
Q3: How would I calculate weight on other planets?
A: Use the same formula but with the planet's gravitational acceleration (e.g., 3.71 m/s² for Mars).
Q4: What units does this calculator use?
A: It uses kilograms for mass, m/s² for gravity, and outputs Newtons for weight.
Q5: How do I convert Newtons to other weight units?
A: 1 Newton ≈ 0.2248 pounds-force. For kg-force, divide Newtons by 9.81.
