The history panel on the side or bottom of the screen lists every calculation from your current session. Click any entry to bring that value into your next calculation.

Is this calculator free?

Yes, completely free with no subscription, login, or payment required.

All calculations run entirely in your browser. Nothing is sent to or stored on our servers.

Does it work on mobile?

Yes. The calculator layout adapts to phone and tablet screens, including touch-optimized button sizing.

Can I copy a result to paste it somewhere else?
