Frequently asked questions
Is this unit converter free?
Yes, and there is no limit on how many times you can use it.
How accurate are the conversions?
Conversions use standard conversion factors (e.g. 1 inch = 2.54cm exactly) and are shown rounded to 6 decimal places.
Can I convert between different categories, like length to weight?
No — units only convert within the same category (length, weight or temperature), since converting between them is not physically meaningful.
Is my data sent to a server?
No. All conversions happen locally in your browser.
