The value of 13 minutes in radians is approximately 0.0038 radians.
To convert minutes to radians, recognize that each degree equals π/180 radians and each degree contains 60 minutes. So, 13 minutes is a fraction of a degree, which then transforms into radians by multiplying with π/180 divided by 60. This conversion allows angular measurements in minutes to be expressed in the standard radian unit used in mathematics and physics.

Conversion Formula
The formula to convert minutes to radians is: radians = minutes * (π / 180) / 60. It works because a degree is divided into 60 minutes, and a radian is based on the ratio of an arc length to its radius, with π/180 converting degrees to radians. So, each minute is a small fraction of a degree, which gets scaled into radians through this formula. For example, converting 13 minutes: 13 * (π / 180) / 60 = approximately 0.0038 radians, which is the angular measure in radians corresponding to 13 minutes.
Conversion Example
- Convert 20 minutes:
- Step 1: Recognize 20 minutes as a fraction of a degree.
- Step 2: Apply the formula: 20 * (π / 180) / 60.
- Step 3: Calculate: 20 * (3.1416 / 180) / 60 ≈ 0.0058 radians.
- Convert 45 minutes:
- Step 1: 45 minutes as part of a degree.
- Step 2: 45 * (π / 180) / 60.
- Step 3: 45 * (3.1416 / 180) / 60 ≈ 0.0131 radians.
- Convert 5 minutes:
- Step 1: 5 minutes in degrees.
- Step 2: 5 * (π / 180) / 60.
- Step 3: 5 * (3.1416 / 180) / 60 ≈ 0.00145 radians.
- Convert 60 minutes:
- Step 1: 60 minutes equals 1 degree.
- Step 2: 1 * (π / 180).
- Step 3: 1 * (3.1416 / 180) ≈ 0.01745 radians.

Conversion Definitions
Minute
A minute is a unit of angular measurement equal to 1/60th of a degree, used to specify small angles in navigation, astronomy, and other fields where precise angular measurements are necessary.
Radian
A radian is the angle created when the arc length of a circle equals the radius, with a full circle being 2π radians, making it the standard unit for measuring angles in mathematical and scientific calculations involving circles and periodic functions.
Conversion FAQs
How accurate is the conversion from 13 minutes to radians?
The conversion is very precise when using the exact formula, but minor discrepancies may occur depending on the number of decimal places used in calculations and the approximation of π. For most practical purposes, rounding to four decimal places is sufficient.
Why do we divide by 60 in the conversion?
Dividing by 60 is necessary because there are 60 minutes in a degree, and converting minutes to radians involves first converting minutes into degrees, then degrees into radians. This two-step process ensures correct angular measurement conversion.
Can I convert any number of minutes to radians with this method?
Yes, this method is applicable universally for any angular measurement in minutes. Just multiply the number of minutes by (π / 180) / 60 to get the equivalent in radians, regardless of the size of the angle.
What is the significance of using radians instead of degrees?
Radians are preferred in higher mathematics and physics because they relate directly to the properties of circles and periodic functions, simplifying calculations involving derivatives and integrals, and providing more natural measures of angles.
