FAQ
How do I convert angle units on this page?+
Choose the starting unit in From, the target unit in To, then type a number. All 6 angle units are in those dropdowns — there is not a separate page for each pair.
Which angle units can I convert?+
Radian (rad), Degree (°), Gradian (gon), Arcminute (′), Arcsecond (″), Turn (tr).
How do I convert degrees to radians?+
Select Degree in From and Radian in To, then enter the value. The result updates immediately.
Why is there one page instead of a page for every conversion?+
One strong converter per category is easier to use and cleaner for search than hundreds of nearly identical pair pages.
