What is an attojoule?

An attojoule is a unit of energy equal to 10^-18 joules, used to measure very small energy amounts such as those at atomic or photon scales.

Why is therm (EC) used for energy measurement?

Therm (EC) is used in Europe for natural gas billing and energy reporting, representing 100,000 British thermal units.

Can I use this conversion for everyday energy calculations?

Due to the large scale difference, this conversion is primarily used in scientific research and energy industry contexts, not for casual everyday calculations.
