## radians to meters conversion

Your question is ambiguous. Radian is a measure

of angle and mm is a measure of distance.

Would you please reformulate your question?

## convert radian to mm

You insist on converting totally incompatible measures such as angle and length ..

Are you serious, or is it just a joke???

## meters to radians conversion

**radian**

has dimensions of

**plane-angle**

Note that plane-angle is not an official metric (SI) dimension

**millimeter**

has dimensions of

**length**

If both the units have same dimensions then only they can be inter changes..

and as**radian**is from**plane angle**and**mm**is from**length**they cann't be converted

## convert radian to mm/m

you need for this question to determine radius of circle then if multiple radius to angle value you have quantity with length dimension as dimension of radius.

## mm to radian

jsps,

Radian ia an angular quantity and is dimensionless. If you are interested in determining the arc length (l) on a circle subtended by an angle in radians, use the formula l = wr, where r is the radius, w is the radian angle.

Regards,

Kral

## convert mm to rad

Mr. Jallem, my friends ask me to convert from temperature to second, could you tell me how?

Glad I'm not that...you know.

Learn trigonometry kid!

Added after 50 seconds:

If you ask steradian to mm, its possible.

## formula to convert mm to french

It's exactly like someone asking how to convert amperes into tomatoes.

TOTALLY INCOMPATIBLE UNITS!

To do a conversion between mm and radians, you need a circle of a known radius (example, using a circle with a 1 meter radius, a radian would measure 1000mm) which is NOT the case in the JSPS's question.
