What does Btu (th) measure?

Btu (th) measures the heat required to raise the temperature of one pound of water by one degree Fahrenheit, using a thermochemical calorie basis.

What is a nanojoule used for?

A nanojoule quantifies very small amounts of energy, such as pulse energy in lasers, energy per operation in microelectronics, or energy stored in micro-scale devices.

Why is the conversion factor so large?

The large conversion factor arises because the Btu (th) represents much larger energy units compared to nanojoules, which measure energy on the billionth-of-a-joule scale.
