A nanojoule (nJ) is a unit of energy equal to one billionth of a joule, often used to measure very small energy quantities like laser pulses or microelectronic events.

What does ton-hour (refrigeration) measure?

Ton-hour (refrigeration) quantifies the cooling energy produced by one refrigeration ton sustained for one hour, commonly used in HVAC and commercial cooling systems.

Why are conversions from nanojoules to ton-hours so small?

Because nanojoules measure extremely small energy amounts, converting to larger units like ton-hours results in very small fractional values.
