About this tool

How to use it
- Choose a category from the Type dropdown, e.g. Length or Currency.
- Type a value in either field and the other converts instantly.
- Switch units within a category using the unit selectors.
- For currency, rates are pulled live so figures reflect the current exchange rate.
FAQ
Is it free to use?
Yes — every conversion here is free and unlimited.
Does it store what I convert?
No. Conversions happen locally in your browser; nothing is sent anywhere except the currency rate lookup itself.
How current are the currency rates?
Rates come from a live feed and are cached for about an hour — fine for estimating, not for trading.
What categories does it cover?
Length, area, volume, mass, temperature, speed, pressure, power, energy, data, time, angle, frequency, force and torque, plus currency.
