Why is the conversion from therm to therm (US) not exactly 1?

Because the two units are based on slightly different BTU definitions and reference conditions, the conversion factor is close to but not exactly 1.

Can this tool be used for natural gas billing?

Yes, it's designed to help convert energy units commonly used in billing residential and commercial natural gas consumption.

Is the therm unit the same in all countries?

No, the therm is a non-SI unit and its exact energy equivalent can vary depending on the BTU standard and regional measurement practices.
