Torque is defined as
a force that tends to rotate or turn things. It can be thought of as rotational
force.
The torque units contain a distance and a force. To calculate the torque, you
multiply the force by the distance from the center.
Torque calculation formula is :
Torque = Distance from the center * Force
Torque unit in SI system is newton meter (nm). Other force units, pound force
foot (lbs ft), ounce inch, kilogram force meter are widely used.
