Terms of Use

Reference only

BTU to Tons is a free reference tool. Its results are unit conversions; they aren't professional advice.

A conversion doesn't tell you whether an AC is the right size for a space, and capacity doesn't determine breaker or wire size. For equipment selection or installation, use a qualified professional, the manufacturer's documentation and the locally adopted codes.

No warranty

We check every formula against published constants, but the site is provided as is, without warranties of any kind. You're responsible for how you use the results.

Changes

We may update the tool and these terms at any time.
