BTU to Ton Calculator

Convert BTU to Refrigeration Ton

This free BTU to Ton calculator helps HVAC technicians, engineers, contractors, and homeowners quickly convert British Thermal Units (BTU) into air conditioning tons. In HVAC systems, cooling capacity is often measured in tons instead of BTU.

What Is BTU?

BTU (British Thermal Unit) measures heat energy. In air conditioning systems, it represents how much heat an AC unit can remove per hour.

What Is a Ton in AC?

One refrigeration ton equals 12,000 BTU per hour. The term originated from the amount of heat required to melt one ton of ice in 24 hours.

BTU to Ton Formula

Ton = BTU ÷ 12,000

Why Proper AC Size Matters

Choosing the correct air conditioner size improves energy efficiency, reduces electricity bills, increases system lifespan, and provides better cooling comfort.
