The result of converting 300 rpm to radians per second is approximately 31.4160 rad/sec.
To convert revolutions per minute (rpm) to radians, the key is understanding that one revolution equals 2π radians, and there are 60 seconds in a minute. So, multiplying rpm by 2π and dividing by 60 gives the radians per second.
Conversion Result and Explanation
300 rpm is about 31.4160 radians per second because each revolution contains 2π radians. Since there are 60 seconds in a minute, multiplying 300 rpm by 2π and dividing by 60 transforms revolutions per minute into radians per second, which is the standard measure of angular velocity.

Conversion Formula
The conversion formula from rpm to rad/sec is: radians per second = rpm * 2π / 60. This works because each revolution is 2π radians, and there are 60 seconds in a minute. Multiplying rpm by 2π gives radians per minute, then dividing by 60 changes to radians per second.
For example, with 300 rpm: 300 * 2π / 60 = (300 * 6.2832) / 60 = 1884.96 / 60 = 31.4160 rad/sec. The calculation ensures that revolutions are properly converted into radians considering the time unit change.
Conversion Example
- Convert 150 rpm:
- Multiply 150 by 2π: 150 * 6.2832 = 942.48 radians per minute.
- Divide by 60 to get radians per second: 942.48 / 60 = 15.7080 rad/sec.
- Convert 45 rpm:
- 45 * 2π = 282.743 radians per minute.
- Divide by 60: 282.743 / 60 = 4.7124 rad/sec.
- Convert 600 rpm:
- 600 * 2π = 3769.91 radians per minute.
- Divide by 60: 3769.91 / 60 = 62.8318 rad/sec.
- Convert 90 rpm:
- 90 * 2π = 565.486 radians per minute.
- Divide by 60: 565.486 / 60 = 9.4248 rad/sec.
- Convert 200 rpm:
- 200 * 2π = 1256.64 radians per minute.
- Divide by 60: 1256.64 / 60 = 20.9440 rad/sec.

Conversion Definitions
rpm
Revolutions per minute (rpm) measure how many complete turns an object makes in one minute, indicating rotational speed. It is a common unit used to describe the speed of motors, wheels, and other rotating parts, relating revolutions to time.
rad
Radian (rad) is a unit of angular measure that defines the angle subtended at the center of a circle by an arc equal in length to the radius. It provides a natural way to express angles based on the circle’s geometry, where 2π radians equal a full revolution.
Conversion FAQs
What is the significance of converting rpm to rad/sec?
Converting rpm to rad/sec helps in analyzing rotational motion mathematically, especially in physics and engineering. It allows for calculations involving angular velocity, torque, and power in a standard SI unit, making it easier to compare and use in formulas.
Why is 2π used in the conversion formula?
Because one revolution is exactly 2π radians, using 2π in the formula converts revolutions into radians, which is a more fundamental measure of angles. This conversion aligns rotational speed with the SI unit for angular measurements.
Can I convert rpm to other angular units easily?
Yes, with the right formulas. For example, converting rpm to degrees per second involves multiplying by 360/60, while to radians per second involves multiplying by 2π/60. Each conversion depends on understanding the relationship between units.
Is there a way to automate rpm to rad/sec conversions?
Yes, using calculator tools or programming scripts like JavaScript, which automatically apply the conversion formula when entering RPM values. This saves time and reduces errors in manual calculations.
