Torque Converter

Convert between newton-meters, pound-feet, and other torque units.

Understanding the Converter

Torque is a measure of the rotational force. It's what causes an object to rotate around an axis. This tool is essential for mechanics, engineers, and physicists for converting between different units of torque.

All conversions use the newton-meter (N·m), the SI unit of torque, as a base reference to ensure accuracy.

Formula Used

Standardized Conversion Process

To ensure accuracy, all conversions use the newton-meter (N·m) as a common base unit.

  1. Convert to Newton-meters: The input value is converted to newton-meters by multiplying it by its conversion factor.
    Value in N·m = Input Value × Conversion Factor to N·m
  2. Convert to Target Unit: The newton-meter value is then converted to the desired final unit by dividing it by the target unit's conversion factor.
    Final Value = Value in N·m / Target Unit's Conversion Factor

A Guide to Units of Torque

Torque, also called moment of force, is the rotational equivalent of linear force. It is defined as a force applied at a distance from a pivot point.

Common Torque Units

UnitAbbreviationDefinition & Context
Newton-meterN·mThe SI unit of torque. It represents the torque from one newton of force applied one meter from the pivot. The standard for scientific and international engineering applications.
Pound-footlbf·ftAn imperial/US customary unit, representing one pound-force applied one foot from the pivot. The standard for automotive engine torque ratings in the US.
Pound-inchlbf·inA smaller imperial/US customary unit, representing one pound-force applied one inch from the pivot. Used for smaller fasteners and applications.

Frequently Asked Questions

Is torque the same as work or energy?

No. While both torque and energy can be expressed in units of force times distance (like newton-meters and joules), they are different concepts. Torque is a vector quantity that causes rotation, while energy (and work) is a scalar quantity representing the capacity to do work. In SI units, torque is always expressed as newton-meters (N·m), while energy is expressed in Joules (J), even though 1 J = 1 N·m dimensionally.

Why is torque important for cars?

Torque is the twisting force an engine produces, and it's what gets your car moving. High torque at low RPMs means the car can accelerate quickly from a standstill. Horsepower (which is related to torque and RPM) determines how fast the car can go.

What is the difference between pound-foot (lbf·ft) and foot-pound (ft·lbf)?

Functionally, they represent the same amount of torque. However, "pound-foot" (lbf·ft) is the more formally correct term for torque, as it emphasizes the unit of force (lbf) being applied at a distance (ft). "Foot-pound" is more commonly associated with work or energy.

How do I use a torque wrench?

A torque wrench is a tool used to apply a specific amount of torque to a fastener like a nut or bolt. You set the desired torque value on the wrench, and it will indicate (often with a click or beep) when you have reached that value, preventing over-tightening or under-tightening.

Summary

The Torque Converter is a crucial tool for mechanics, engineers, and physicists, allowing for quick and accurate conversions between the metric and imperial units of rotational force. It's essential for everything from tightening a bolt to designing an engine.
