## How to Convert Radians to Minutes of Arc

To convert a measurement in radians to a measurement in minutes of arc, multiply the angle by the following conversion ratio: 3,437.746771 minutes of arc/radian.

Since one radian is equal to 3,437.746771 minutes of arc, you can use this simple formula to convert:

minutes of arc = radians × 3,437.746771

The angle in minutes of arc is equal to the angle in radians multiplied by 3,437.746771.

**For example,**here's how to convert 5 radians to minutes of arc using the formula above.

### How Many Minutes of Arc Are in a Radian?

There are **3,437.746771** minutes of arc in a radian, which is why we use this value in the formula above.

1 rad = 3,437.746771'

Radians and minutes of arc are both units used to measure angle. Keep reading to learn more about each unit of measure.

## What Is a Radian?

A radian is the measurement of angle equal to the length of an arc divided by the radius of the circle or arc.^{[1]} 1 radian is equal to 180/π degrees, or about 57.29578°. There are about 6.28318 radians in a circle.

The radian is the SI derived unit for angle in the metric system. Radians can be abbreviated as *rad*, and are also sometimes abbreviated as * ^{c}*,

*r*, or

*. For example, 1 radian can be written as 1 rad, 1*

^{R}^{c}, 1 r, or 1

^{R}.

Radians are often expressed using their definition.
The formula to find an angle in radians is θ = s/r, where the angle in radians *θ* is equal to the arc length *s* divided by the radius *r*.
Thus, radians may also be expressed as the formula of arc length over the radius.

Radians are also considered to be a "unitless" unit. That is, when multiplying or dividing by radians, the result does not include radians as part of the final units.

For example, when determining the length of an arc for a given angle, we use the formula above, rearranged to be s = θr. If θ is in radians and r is in meters, then the units of s will be meters, not radian-meters. If θ were in degrees, however, then s would have units of degree-meters.

## What Is a Minute of Arc?

The minute of arc is a unit of angle equal to 1/60th of one degree, or 1/21,600 of a circle. The minute of arc is also equal to π/10,800 radians.

A minute of arc is sometimes also referred to as an arc minute, arcminute, or minute arc. Minutes of arc can be abbreviated as *arcmin*, and are also sometimes abbreviated as *MOA* or *amin*. For example, 1 minute of arc can be written as 1 arcmin, 1 MOA, or 1 amin.

The minute of arc is most commonly represented using the prime (′), although the single-quote is commonly used. For instance, 1 minute of is most commonly expressed as 1′.
