1×10⁻⁵J
Nothing on our list is smaller: one heartbeat is 100,000× more. That could lift a one-tonne car 1.02×10⁻⁹ m into the air.
What it means
What could that energy do?
The hill climb ignores friction and assumes a 1,000 kg car. Food calories on labels are kilocalories.
The math
How to convert erg to J
To convert ergs to joules, multiply by 1×10⁻⁷.
Example: 100 erg × 1×10⁻⁷ = 1×10⁻⁵ J.
In the other direction, 1 J = 10,000,000 erg.

The units
About these units
Ergs (erg)
An erg is a ten-millionth of a joule, the energy unit of the old centimeter-gram-second system. A mosquito in flight uses a few ergs per second.
Joules (J)
The joule is the SI unit of energy: the work done pushing with one newton over one meter. Lifting an apple a meter takes about one joule.
