Frequently asked
Is my input sent anywhere?
No. Every conversion is plain arithmetic, done in this tab. Nothing is sent anywhere.
How accurate are these conversions?
They use standard, precise conversion factors (e.g. 1 inch = 2.54cm exactly). Results are rounded to 6 decimal places for display.
Why can't I convert between categories?
Length, weight, temperature, and volume are physically different quantities. Converting between them wouldn't mean anything.
