Torque Conversions
Converting torque values from one unit to another is often necessary when working with torque measurements to ensure consistency and accuracy. Torque, a fundamental concept in physics and engineering, is a measure of rotational force or the turning effect of a force. It is crucial in various applications, from automotive and mechanical engineering to industrial machinery. This article explores the torque conversion process and provides an automated torque conversion calculator and downloadable charts.

Understanding torque units
Torque can be measured using different systems of measurement. It is important to convert between these units accurately to ensure compatibility and precision in torque measurements. The most commonly used units for torque are:
- International System of Units (SI):
- Newton-meter (Nm)
- Kilogram-force meter (kgf.m)
- Imperial System
- Pound-food (lb.ft)
- Inch-pound (in.lb)
Conversion factors
The user should understand the conversion factors specific to each unit to convert torque from one unit to another. Here are the conversion factors for commonly encountered torque units:
- 1 ozf.in = 0.0625 lbf.in
- 1 lbf.in = 16 ozf.in
- 1 lbf.ft = 12 lbf.in
- 1 mN.m = 0.1416 ozf.in
- 1 cN.m = 1.416 ozf.in
- 1 Nm = 141.61 ozf.in
- 1 gf.cm = 0.01388 ozf.in
- 1 kgf.cm = 13.887 ozf.in
- 1 kgf.m = 1388.73 ozf.in
Example
To convert 30 ounce-force inches (ozf.in) to pound-force inches (lbf.in):
1 ozf.in = 0.0625 lbf.in
30 ozf.in * 0.0625 lbf.in/ozf.in = 1.875 lbf.in
