dear frnds,
plz tell me formula to convert radian or degree to mm or cm.............its very much required in my frnd's project.........

regards
JSPS

dear frnd,
i want to convert radian to mm

regards
JSPS

of angle and mm is a measure of distance.

degree to mm conversion

no mr. jallem,
question is correct..........

JSPS

You insist on converting totally incompatible measures such as angle and length ..
Are you serious, or is it just a joke???

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

look at:
h**p://www.themathpage.com/aTrig/arc-length.htm

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.

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.

Some people are just stuborn......

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

Learn trigonometry kid!

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.

An arc characterized by an angle of A radian and having a radius of R meter has a length equal to AxR meter.
Your question was not too complicated to be misunderstood.
