The calculator above uses the conversion ratios below.
Air-conditioner capacity conversion ratios
To convert air-conditioner BTU to Ton, kW, and vice-versa, use the following conversion ratios:
- 1 Ton =3.517kW
- 1 Ton =12,000 BTU
Alternatively, you can refer to the table below to easily convert common air-conditioner capacities in Ton to BTU and kW and vice-versa.

Table showing equivalent BTU and KW capacities for selected air-conditioner capacities (Ton)
- The 9,000 and 12,000 BTU air-conditioners are usually available in both the 115V and 208-230VAC versions.
- Air conditioners with cooling capacity higher than 12,000 BTU are in the higher 208-230VAC range.
