How do you convert revolutions to arcminutes?

To convert revolutions (rev) to arcminutes (′), multiply the angle in revolutions by 21,600 (arcminutes = revolutions × 21,600).

What is 5 revolutions in arcminutes?

5 revolutions (5 rev) is equal to 108,000 arcminutes (108,000 ′).

Which is larger, 1 revolution (turn) (rev) or 1 minute of arc (′)?

One revolution (turn) (rev) is larger than one minute of arc (′). Specifically, 1 rev contains 21,600 ′, whereas 1 ′ is 0.00004629 rev.

How do I convert back from arcminutes (′) to revolutions (rev)?

To reverse the calculation from ′ to rev, multiply your minute of arc value by the inverse factor 0.00004629 (or divide by 21,600). You can also click the Swap button in the tool above to flip directions in one click.

How many decimal places should I round rev to ′ results to?

For everyday comparisons and quick estimates, rounding to 2 decimal places is usually sufficient (for example, 5 rev ≈ 108,000.00 ′). For engineering, laboratory, or machining specifications, select 4 or 6 decimals—or Scientific (10ⁿ) mode—in the calculator toolbar above.

How to Convert Revolutions to Arcminutes

To convert revolutions to arcminutes, multiply the angle by the following conversion ratio: 21,600 arcminutes/revolution.

Since one revolution is equal to 21,600 arcminutes, you can use this simple formula to convert:

arcminutes = revolutions × 21,600

The angle in arcminutes is equal to the angle in revolutions multiplied by 21,600.

For example, here's how to convert 5 revolutions to arcminutes using the formula above.

arcminutes = (5 rev × 21,600) = 108,000 ′

How Many Arcminutes Are in a Revolution?

There are 21,600 arcminutes in a revolution, which is why we use this value in the formula above.

1 rev = 21,600 ′|1 ′ = 0.000046296 rev

Our revolution to minute of arc calculator automatically converts your angle measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Revolutions and arcminutes are both units used to measure angle. Keep reading to learn more about each unit.

What Is a Revolution?

A revolution is a unit of angle equal to 360 degrees (°), the base unit for angle. Complete 360° circle (2π radians). [1]

The revolution is classified as a standard unit of angle. Revolutions can be abbreviated as rev; for example, 1 revolution can be written as 1 rev.

When working with revolutions (rev) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, revolutions (rev) are widely used across standard angle applications within international standard workflows, engineering documentation, and technical data sheets.

What Is a Minute of Arc?

A minute of arc is a unit of angle equal to 1/60 of a degree (0.0166667 °). 1/60 of a degree. [2]

The minute of arc is classified as a standard unit of angle. Arcminutes can be abbreviated as ′; for example, 1 minute of arc can be written as 1 ′.

When working with arcminutes (′) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, arcminutes (′) are widely used across standard angle applications within international standard workflows, engineering documentation, and technical data sheets.

Learn more about arcminutes in our Angle Converter.

When converting angle between revolutions (rev) and arcminutes (′), keep full floating-point precision (1 rev = 21,600 ′; 1 ′ = 0.000046296 rev) during intermediate calculations and round only the final minute of arc figure to match your instrument tolerance.
