Converting 60 rpm to radians gives approximately 6.2832 radians.
Table of Contents
Since there are 2π radians in a full rotation and 60 revolutions per minute (rpm), the conversion involves multiplying rpm by 2π and then dividing by 60 to get radians per second. This means 60 rpm equals 2π radians per second, which is about 6.2832 radians.

Conversion Formula
The conversion formula from rpm to rad/s is: radians per second = rpm × (2π) / 60. This works because one revolution equals 2π radians, and there are 60 seconds in a minute. By multiplying rpm by 2π, you convert revolutions to radians, then dividing by 60 adjusts for seconds.
For example, to convert 30 rpm: 30 × (2π) / 60 = (30 × 6.2832) / 60 = 188.496 / 60 ≈ 3.1416 rad/sec. This step-by-step math shows how the conversion yields the angular velocity in radians per second.
Conversion Example
- Convert 45 rpm to rad/sec:
- Multiply 45 rpm by 2π: 45 × 6.2832 ≈ 282.7432
- Divide by 60: 282.7432 / 60 ≈ 4.7124 rad/sec
- Convert 90 rpm to rad/sec:
- Multiply 90 by 2π: 90 × 6.2832 ≈ 565.488
- Divide by 60: 565.488 / 60 ≈ 9.4248 rad/sec
- Convert 15 rpm to rad/sec:
- Multiply 15 by 2π: 15 × 6.2832 ≈ 94.248
- Divide by 60: 94.248 / 60 ≈ 1.5708 rad/sec
- Convert 75 rpm to rad/sec:
- Multiply 75 by 2π: 75 × 6.2832 ≈ 471.238
- Divide by 60: 471.238 / 60 ≈ 7.8539 rad/sec
- Convert 120 rpm to rad/sec:
- Multiply 120 by 2π: 120 × 6.2832 ≈ 753.982
- Divide by 60: 753.982 / 60 ≈ 12.566 rad/sec

Conversion Definitions
rpm
Revolutions per minute (rpm) measures how many full turns an object makes each minute. It indicates rotational speed, with higher rpm meaning faster spinning. Used in engines, motors, and rotating equipment to specify speed in a time-based manner.
rad
Rad, short for radians, is a measurement of angles based on the radius of a circle. One radian equals the angle at which the arc length equals the radius. It’s used in mathematical calculations involving circles, rotations, and angular velocities.
Conversion FAQs
How does rpm relate to angular velocity in radians per second?
RPM measures revolutions per minute, while radians per second quantify how fast an object rotates in angular terms. To convert, multiply rpm by 2π and divide by 60, translating revolutions into radians and seconds into the time frame.
Why is 60 rpm equal to approximately 6.2832 radians?
Because 60 rpm means 60 revolutions in a minute, and each revolution equals 2π radians. Multiplying 60 by 2π gives 120π radians per minute, then dividing by 60 seconds yields 2π radians per second, which is about 6.2832 radians.
Can I use this conversion for any rpm value?
Yes, the formula rpm × (2π) / 60 works for any rpm, converting rotational speed into radians per second. Just plug in the rpm value into the formula for accurate angular velocity in radians.
What practical applications use rpm to rad conversions?
This conversion is crucial in engineering, physics, and mechanics, where understanding rotational speeds in radians per second helps analyze angular acceleration, torque, and rotational energy in motors and mechanical systems.
