Measurement units

Using USD and Imperial. You can change either choice.

Currency changes the unit of your amounts, not their value. No exchange rate or country-specific tax, benefit, or lending rule is applied. Money results and loan schedules retain the calculators’ two-decimal precision; this does not apply local cash-rounding rules.

Measurement changes convert valid existing quantities. Incomplete entries stay as typed; finish them using the units shown. Other units stay as labeled. Enter numbers as 1,234.56; a decimal comma is not supported.

Initial suggestions use only your browser’s language region. Choices are saved on this browser; no location lookup is used.
