What does 1 kilojoule equal in Btu (th)?

One kilojoule equals approximately 0.9484516527 Btu (th), based on the thermochemical calorie definition.

Why should I use Btu (th) for heating systems?

Btu (th) is traditionally used to rate heating and cooling equipment capacity and energy content of fuels, making it standard in HVAC industries.

Can this converter be used for precise thermodynamic calculations?

While useful for general conversions, slight inaccuracies can occur due to definition differences; verify unit details for high-precision needs.
