The result of converting 900 rpm to radians per second is approximately 94.2480 radians/sec.
To convert revolutions per minute (rpm) into radians per second (rad/sec), you multiply the rpm value by 2π (since one revolution equals 2π radians) and divide by 60 (since there are 60 seconds in a minute). So, 900 rpm equals (900 * 2π) / 60, which simplifies to 94.2480 rad/sec.
Conversion Result
900 rpm equals about 94.2480 radians per second when converted correctly.

Conversion Formula
The formula to convert rpm into rad/sec is: radians/sec = (rpm * 2π) / 60. This works because one revolution is 2π radians, and there are 60 seconds in a minute. By multiplying rpm by 2π, we get radians per minute, then dividing by 60, we get radians per second. For example, 900 rpm: (900 * 2π) / 60 = 94.2480 rad/sec.
Conversion Example
- Convert 150 rpm:
- Multiply 150 by 2π: 150 * 6.2832 = 942.48 radians/minute.
- Divide 942.48 by 60: 15.708 radians/sec.
- Result is approximately 15.708 rad/sec.
- Convert 45 rpm:
- 45 * 6.2832 = 282.84 radians/minute.
- Divide 282.84 by 60: 4.714 radians/sec.
- Result is about 4.714 rad/sec.
- Convert 720 rpm:
- 720 * 6.2832 = 4523.89 radians/minute.
- Divide by 60: 75.398 radians/sec.
- Result is approximately 75.398 rad/sec.

Conversion Definitions
rpm (revolutions per minute) measures how many full turns an object makes in one minute. It indicates rotational speed, often used in engines, motors, and turbines to describe how fast something spins.
Rad (radian) is a measure of angular distance, representing the angle created when the arc length equals the radius. One radian is about 57.2958 degrees, used in mathematics and physics to quantify rotation.
Conversion FAQs
Why does the conversion from rpm to rad/sec use 2π?
This is because a complete revolution equals 2π radians. Multiplying rpm by 2π converts revolutions into radians, which are a more fundamental measure of angles, and dividing by 60 adjusts for seconds, converting per minute into per second.
Can I convert other rotational speeds using this method?
Yes, the same formula applies for any rpm value. Just substitute the rpm into the formula (rpm * 2π) / 60, and it will give you the rad/sec equivalent, regardless of the number.
What if I need to convert rad/sec back to rpm?
To reverse the process, multiply rad/sec by 60 and divide by 2π: rpm = (rad/sec * 60) / 2π. This allows you to switch between these units based on your needs.
Is there a quick way to estimate radians/sec from rpm?
Yes, for quick estimates, multiply rpm by approximately 0.10472 (which is 2π/60). So, 900 rpm roughly equals 900 * 0.10472 ≈ 94.248 rad/sec.
What is the significance of converting rpm to rad/sec?
This conversion is essential in physics and engineering to perform calculations involving angular velocity, rotational kinetic energy, and torque, as radians provide a natural measure for angles in these contexts.
