# Torque

The force that can cause an object to rotate along an axis is measured as torque. In linear kinematics, force is what drives an object's acceleration. Similar to this, an angular acceleration is brought on by torque. As a result, torque can be thought of as the rotational counterpart to force. The axis of rotation is a straight line about which an item rotates.

Torque in physics is only a force's propensity to turn or twist. Torque is referred to using a variety of terms, including moment and moment of force. Sometimes referred to as the moment arm or lever arm, the distance between the point of application of force and the axis of rotation.

## Examples

Here are 5 examples of torque in real life.

1. When opening or closing a bottle lid with a twist.

2. When a pencil is gripped and turned within a sharpener. Torque is what makes any device with a crank operate.

3. When you quickly pull on the thread to spin a top.

4. The engine's torque is what causes a car to accelerate or pull away from a stop.

## Units of Torque

Newton-meters, or N*m, are the SI units used in the International System of Measurement (SI) to measure torque. Since torque is not work or energy, even though newton-meters and joules are equivalent, all measurements should be given in newton-meters.  M is used to indicate it when it is referred to as the moment of force. Pound-force-feet (lbft) is a common abbreviation for pound-foot in imperial units, with the word "force" implied.

### The Right-Hand Torque Rule

Working with torque can be challenging because it is calculated using a vector product. The change in angular velocity is in the direction of the torque because the torque is in the direction of the angular velocity that would be produced by it. Use your right hand, curling your fingers in the force's direction of rotation while pointing your thumb in the torque vector's direction.

## Torque Converter

You can convert torque measurements using a Torque converter from one unit measurement type to another. The twisting force known as torque frequently results in rotation. The torque is calculated by multiplying the force exerted and the distance from the point of application. Because of this, the torque value is expressed in units of force and length, such as 15 lbf.ft. Torque values expressed in ounces and inches will be smaller than those expressed in feet and pounds or yards and tonnes.

Use this calculator to quickly convert units between different torque measurement scales. Units may be converted from one measurement system to another, such as from dyne centimeter to kgrf meter, Newton meter to dyne centimeter, Newton meter to Lbf foot etc.
