Radian to Degree Converter
Convert radians to degrees instantly. Free, bidirectional, and fully in-browser.
1 radian equals 57.29577951 degrees — enter any radian value to convert it to degrees instantly. This Radian to Degree converter is a client-side tool: it applies a single multiplication (° = rad × 57.29577951) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert degrees back to radians. A reference table lists common radian values already converted, and nothing you enter is sent to a server.

Why use Radian to Degree Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to degree → radian without reloading.
Exact Angle math
The conversion uses the precise factor (° = rad × 57.29577951), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a radian measurement to degrees for a spec, listing, or report.
- Checking radian↔degree figures while comparing products, datasets, or documentation.
- Learning the radian-to-degree relationship from the worked formula and the common-value table.
Frequently asked questions
How many degrees are in a radian?
One radian is 57.29577951 degrees. Multiply the radian value by 57.29577951 to convert. For example, 10 rad = 572.9577951 °.
What is the formula to convert radians to degrees?
° = rad × 57.29577951. This tool applies it automatically and shows a worked example: 10 rad = 572.9577951 °.
Can it convert degrees back to radians?
Yes. Press the swap button, or type into the degree field, and the tool converts degrees to radians using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard angle and rotation definition (° = rad × 57.29577951), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
