What does 1 megajoule represent?

1 megajoule (MJ) is an SI derived unit of energy equal to one million joules used for measuring work, heat, chemical energy, and electrical energy.

What is a ton-hour (refrigeration)?

A ton-hour (refrigeration) measures the cooling effect produced by one refrigeration ton for one hour, quantifying heat removed by refrigeration or air-conditioning systems.

Why convert megajoules to ton-hours (refrigeration)?

Converting helps engineers and energy managers relate general energy input or output to cooling system performance and energy consumption.

Can I use this conversion for non-cooling energy?

Ton-hour (refrigeration) is specialized for cooling energy and may not be applicable for other forms of energy without additional context.
