Why convert Btu (th)/hour to kilojoule/hour?

Converting to kilojoule/hour allows expressing heat transfer rates using SI units, which improves compatibility with scientific calculations and international standards.

What is the conversion rate from Btu (th)/hour to kilojoule/hour?

The conversion rate is 1 Btu (th)/hour equals 1.05435 kilojoule/hour.

Can this conversion be used for large power values?

Kilojoule/hour is more suitable for small to moderate power rates; for very large power values, units like kilowatts are generally preferred.
