1. What is Torque Calculation?

Torque is a measure of the turning force on an object. This calculator converts kilogram-force at a distance to Newton-meters (Nm), the standard unit for torque.

2. How Does the Calculator Work?

The calculator uses the torque equation:

Where:

• \( Weight \) — Mass in kilograms (kg)
• \( 9.80665 \) — Acceleration due to gravity (m/s²)
• \( Distance \) — Lever arm length in meters (m)

Explanation: The equation converts the force (from kg to Newtons) and multiplies by the distance to get torque in Newton-meters.

3. Importance of Torque Calculation

Details: Torque calculations are essential in engineering, mechanics, and physics for designing and analyzing rotating systems like engines, bolts, and mechanical assemblies.

4. Using the Calculator

Tips: Enter weight in kilograms and distance in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why 9.80665 in the formula?
A: This is the standard acceleration due to gravity (1 kg-force = 9.80665 Newtons).

Q2: What are typical torque values?
A: Torque values vary widely - from small electronics (<1 Nm) to large industrial machinery (>1000 Nm).

Q3: Can I use this for bolt tightening?
A: Yes, this gives the theoretical torque, but actual bolt torque should consider friction and other factors.

Q4: What's the difference between Nm and kg-cm?
A: 1 Nm = 10.1972 kg-cm. This calculator gives results in the standard SI unit (Nm).

Q5: Does direction matter in torque calculation?
A: The calculator gives magnitude only. Direction (clockwise/counter-clockwise) is important in applications but not in this basic calculation.
