Elara Bennett2000 rpm equals approximately 209.44 radians per second.
To convert revolutions per minute (rpm) to radians per second (rad/s), multiply the rpm value by 2π and then divide by 60 because there are 2π radians in one revolution and 60 seconds in a minute. For 2000 rpm, the calculation is (2000 × 2π) / 60, which results in about 209.44 rad/s.

Conversion Formula
The formula to convert rpm to rad is (rpm × 2π) / 60. This works because each revolution contains 2π radians, and there are 60 seconds in a minute. By multiplying rpm by 2π, we get radians per minute, then dividing by 60 converts it to radians per second.
For example, with 2000 rpm: (2000 × 2π) / 60 = (2000 × 6.2832) / 60 = 12566.4 / 60 ≈ 209.44 rad/sec. This step-by-step math shows how the conversion accounts for the full circle in radians and the time units.
Conversion Example
- Convert 1500 rpm to rad/sec:
- Multiply 1500 by 2π: 1500 × 6.2832 = 9424.8
- Divide by 60: 9424.8 / 60 = 157.08 rad/sec
- Result: 1500 rpm equals about 157.08 rad/sec
- Convert 3000 rpm to rad/sec:
- Multiply 3000 by 2π: 3000 × 6.2832 = 18849.6
- Divide by 60: 18849.6 / 60 = 314.16 rad/sec
- Result: 3000 rpm equals about 314.16 rad/sec
- Convert 2500 rpm to rad/sec:
- Multiply 2500 by 2π: 2500 × 6.2832 = 15708
- Divide by 60: 15708 / 60 = 261.80 rad/sec
- Result: 2500 rpm equals approximately 261.80 rad/sec

Conversion Definitions
rpm (revolutions per minute) measures how many complete turns an object makes in a minute, showing rotational speed. It indicates how fast something spins or rotates around an axis, commonly used in motors, engines, and mechanical systems.
Rad (radian) is a unit of angular measurement representing the angle created when the arc length equals the radius. One radian is approximately 57.2958 degrees, and it quantifies the size of angles in circular or rotational motion.
Conversion FAQs
Why do we divide by 60 in the conversion process?
Dividing by 60 converts the speed from per minute to per second, since there are 60 seconds in a minute. This ensures the angular velocity is expressed in radians per second, which is standard in physics and engineering calculations.
Can I use this conversion for non-rotational applications?
No, this formula applies only to rotational systems where rpm and radians describe angular motion. For linear speeds or other units, different conversions are necessary.
What happens if I input a negative rpm value?
A negative rpm indicates rotation in the opposite direction. The conversion will yield a negative rad/sec, signifying reverse rotation, which might be relevant in certain mechanical analyses.
Is this conversion valid for very high rpm values?
Yes, mathematically the formula applies regardless of the rpm size, but at extremely high values, physical limitations or mechanical constraints might affect the actual angular velocity or system behavior.
How accurate is this conversion for precision engineering?
The calculation uses a constant π value and basic arithmetic, providing a highly accurate result for most practical purposes, but for ultra-precise needs, consider using more precise π approximations or computational tools.
