get in the angle in radians listed below to acquire the worth converted to revolutions. The calculator supports values containing decimals, fractions, and π: (π/2, 1/2π, etc)


To transform a radian measurement to a change measurement, multiply the angle by the counter ratio.

due to the fact that one radian is same to 0.159155 revolutions, you have the right to use this straightforward formula to convert:

Radians and revolutions space both units provided to measure up angle. Keep reading to learn much more about each unit that measure.

A radian is the measure up of angle equal to the begin to the end of one arc split by the radius that the circle or arc.<1> 1 radian is same to 180/π, or about 57.29578°. There are about 6.28318 radians in a circle.

The radian is the SI acquired unit for angle in the metric system. Radians can be abbreviated as rad, and are additionally sometimes abbreviated together c, r, or R. For example, 1 radian deserve to be written as 1 rad, 1 c, 1 r, or 1 R.

Radians are often expressed using their definition. The formula to uncover radians is θ = s/r, whereby the angle in radians θ is equal to the arc size s split by the radius r. Thus, radians may likewise be expressed as the formula the arc size over the radius.

A revolution, or turn, is equal to 1 rotation about a circle, or 360°. Revolutions are typically used to measure the rate of rotation, for example when measuring the revolutions per minute (RPM) of a vehicle"s engine.

A transformation is sometimes also referred to together a turn, cycle, or complete rotation. Revolutions have the right to be abbreviated as r, and are also sometimes abbreviated as rev or cyc. Because that example, 1 revolution can be written as 1 r, 1 rev, or 1 cyc.
