Example

The scientist measured the energy output in ergs during the experiment.

Conversation

I just learned about the concept of an erg in my physics class.

Oh really? What exactly is an erg?

It's a unit of energy, equal to the work done by a force of one dyne over one centimeter.

That's interesting! I didn't know there were so many different units of measurement.
