About Torque Converters & Conversion Physics
A Torque Converter serves two distinct definitions depending on whether you are referring to engineering physics or automotive mechanical engineering:
- Unit of Torque Conversion: In physics and mechanical design, torque measures the rotational force applied around an axis (calculated as Force × Distance). Torque is expressed in SI units such as Newton-meters (N·m) or Imperial units such as Pound-feet (lb-ft) and Pound-inches (lb-in).
- Automotive Fluid Coupling: In automatic transmission vehicles, a torque converter is a donut-shaped hydrodynamic fluid coupling that connects the engine crankshaft to the transmission input shaft. It allows the engine to spin independently while the vehicle is idling at a complete stop, and multiplies engine torque during initial launch acceleration.
Key Torque Conversion Factors Table
| From Unit | To Unit | Multiplier |
|---|---|---|
| Newton-meter (N·m) | Pound-foot (lb-ft) | 0.737562 |
| Pound-foot (lb-ft) | Newton-meter (N·m) | 1.355818 |
| Pound-foot (lb-ft) | Pound-inch (lb-in) | 12.0 |
| Kilogram-force meter (kgf·m) | Newton-meter (N·m) | 9.80665 |
