About Dahaebom

Dahaebom is a free site of everyday calculators: how old your dog is in human years, your one rep max, a new tire size, when to go to bed, your running pace. No sign-up, nothing to install.

Under each result we show how it was calculated and which formula or published table it uses, so you can follow where the number comes from instead of taking it on trust.

How we calculate

• Each calculator names its formula and source (for example, the AKC dog age chart or the Epley formula)
• Everything is calculated in your browser. What you enter is never sent to a server
• Results are for general information only and aren't medical, legal or professional advice

Who makes it

Dahaebom is made by Ullim, a small studio that makes mobile games and apps.
