What is an erg and where is it commonly used?

An erg is the CGS unit of energy equal to 1×10⁻⁷ joule, often used in astrophysics, classical mechanics, and electromagnetism for small-scale energy measurements.

What does therm (US) measure and where is it applied?

Therm (US) is a unit of heat energy used primarily in the United States for natural gas billing, furnace sizing, and industrial energy calculations.

Why do conversions from erg to therm (US) result in very small values?

Because an erg is an extremely small energy unit compared to the large scale of therm (US), resulting in very small decimal numbers in the conversion.

How to Convert from Erg to Therm (US)?
