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


To transform a radian measurement to a revolution measurement, main point the angle by the conversion ratio.

because one radian is equal to 0.159155 revolutions, you have the right to use this an easy formula to convert:

Radians and also revolutions room both units supplied to measure up angle. Keep reading to learn an ext about every unit of measure.

A radian is the measure up of angle same to the start to the finish of one arc separated by the radius that the one 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 have the right to be abbreviated together rad, and are additionally sometimes abbreviated together c, r, or R. For example, 1 radian can be composed as 1 rad, 1 c, 1 r, or 1 R.

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

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

A revolution is sometimes additionally referred to as a turn, cycle, or finish rotation. Revolutions have the right to be abbreviated as r, and also are additionally sometimes abbreviated together rev or cyc. For example, 1 change can be written as 1 r, 1 rev, or 1 cyc.
