What does Btu (th) stand for?

Btu (th) means thermochemical British thermal unit, a unit of energy used to describe heat required to raise water temperature and related fuel energy content.

Why use gigaton for energy?

Gigaton is used to describe extraordinarily large energy releases like nuclear explosions or asteroid impacts where standard energy units are impractical.

Can I use this tool for precise energy calculations?

No, due to the massive scale difference, the converter is best for approximate, order-of-magnitude energy comparisons.
