2000 rpm is equivalent to approximately 209.44 radians per second
Converting 2000 rpm to radians involves understanding that rpm measures revolutions per minute, while radians per second quantify rotational angle over time. Since 1 revolution equals 2π radians and there are 60 seconds in a minute, the conversion uses these factors to change rpm into rad/sec.
Introduction
Rotational speed in rpm indicates how many full turns a rotating object makes each minute, whereas radians per second measure the angle it sweeps per second. To convert rpm to rad/sec, the revolutions are converted into radians, and minutes are converted into seconds, resulting in a precise angular velocity.

Conversion Formula
The formula to convert rpm to rad/sec is: radians per second = (rpm × 2π) / 60. This works because each revolution is 2π radians, and dividing by 60 converts minutes into seconds. So, multiplying rpm by 2π gives radians per minute, then dividing by 60 yields radians per second.
For example, if rpm is 2000, then:
- Multiply 2000 by 2π: 2000 × 6.2832 ≈ 12,566.37 radians per minute.
- Then divide by 60: 12,566.37 / 60 ≈ 209.44 rad/sec.
This method ensures an accurate conversion from revolutions per minute to angular velocity in radians per second.
Conversion Example
- Convert 100 rpm to rad/sec:
- Multiply 100 by 2π: 100 × 6.2832 ≈ 628.32.
- Divide by 60: 628.32 / 60 ≈ 10.47 rad/sec.
- Convert 500 rpm to rad/sec:
- Multiply 500 by 2π: 500 × 6.2832 ≈ 3,141.59.
- Divide by 60: 3,141.59 / 60 ≈ 52.36 rad/sec.
- Convert 750 rpm to rad/sec:
- Multiply 750 by 2π: 750 × 6.2832 ≈ 4,712.39.
- Divide by 60: 4,712.39 / 60 ≈ 78.54 rad/sec.

Conversion Definitions
rpm
Revolutions per minute (rpm) measures how many full turns an object completes in one minute. It’s used to indicate rotational speeds in engines, motors, and wheels, and provides a straightforward way to quantify how fast something spins over time.
rad
Radians (rad) are a unit of angular measurement representing the angle of a full circle, which is 2π radians. They are used in mathematics and physics to describe rotational quantities and are essential for calculating rotations, oscillations, and angular velocities.
Conversion FAQs
How accurate is the conversion from 2000 rpm to rad/sec?
The conversion is precise because it relies on fundamental constants: 2π radians per revolution and 60 seconds per minute. As long as the input rpm is correct, the rad/sec value calculated will be accurate to several decimal places.
Can I convert any rpm value into rad/sec using this method?
Yes, the same formula applies universally. Just multiply the rpm value by 2π and divide by 60 to get the angular velocity in radians per second, regardless of whether the rpm is high or low.
Why does the conversion involve dividing by 60?
Dividing by 60 converts the time unit from minutes to seconds, which is necessary because rad/sec measures the angle in radians per second. Without this step, the units would not align correctly, leading to inaccurate results.
