Joule Unit Conversions

What is the Joule unit?

The joule (symbol: J) is the unit of energy in the International System of Units (SI), a measure of the capacity to do work or generate heat.

It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second.

J = kg·m2/s2= N·m = Pa·m3 = W·s = C·V = V·A·s

1 J = 1 N.m

The amount of energy one utilizes in lifting a cup of water from the table to one's mouth equals approximately 1 Joule.

One gram of gasoline releases about 50 kJ on combustion in air.

One ton of TNT releases 4.184 GJ on exploding.
