About this tool
Radian to Milliradian Converter
Convert radians to milliradians instantly. Free, bidirectional, and fully in-browser.
1 radian equals 1000 milliradians — enter any radian value to convert it to milliradians instantly. This Radian to Milliradian converter is a client-side tool: it applies a single multiplication (mrad = rad × 1000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert milliradians back to radians. A reference table lists common radian values already converted, and nothing you enter is sent to a server.
How to use Radian to Milliradian Converter
- 1
Open Radian to Milliradian Converter on AltFTool — it loads instantly in your browser.
- 2
Type the value you want to convert into the Radian field.
- 3
Read the equivalent in milliradians in the result field, and copy it if needed.
- 4
Use the decimal-places slider for more or less precision, or press swap to convert milliradians to radians.
Why use Radian to Milliradian Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to milliradian → radian without reloading.
Exact Angle math
The conversion uses the precise factor (mrad = rad × 1000), 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 milliradians for a spec, listing, or report.
- Checking radian↔milliradian figures while comparing products, datasets, or documentation.
- Learning the radian-to-milliradian relationship from the worked formula and the common-value table.
Frequently asked questions
How many milliradians are in a radian?
One radian is 1000 milliradians. Multiply the radian value by 1000 to convert. For example, 10 rad = 10000 mrad.
What is the formula to convert radians to milliradians?
mrad = rad × 1000. This tool applies it automatically and shows a worked example: 10 rad = 10000 mrad.
Can it convert milliradians back to radians?
Yes. Press the swap button, or type into the milliradian field, and the tool converts milliradians to radians using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard angle and rotation definition (mrad = rad × 1000), 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.
