1800 rpm is approximately 188.50 radians per second (rad)
Converting 1800 rpm to rad involves multiplying by the factor (2π / 60), which converts revolutions per minute to radians per second. When you do this, 1800 rpm equals about 188.50 rad/sec. This allows understanding of rotational speed in standard angular measurement units used in physics and engineering.
Understanding the conversion from rpm to rad
The conversion from rpm (revolutions per minute) to radians involves recognizing that one revolution equals 2π radians. To convert rpm to radians per second, you multiply the rpm value by 2π to get radians per minute, then divide by 60 to convert minutes to seconds. For example, 1800 rpm times 2π gives the radians per minute, then dividing by 60 yields radians per second, about 188.50 rad/sec.

Conversion Formula
The formula to convert rpm to rad is: radians per second = rpm * (2π) / 60. This works because each revolution equals 2π radians, and there are 60 seconds in a minute. Multiplying rpm by 2π gives radians per minute, then dividing by 60 converts it to radians per second. For example, 1800 rpm multiplied by 2π gives 11309.73 radians per minute, divided by 60 equals 188.50 rad/sec.
Conversion Example
- Convert 1500 rpm:
- Multiply by 2π: 1500 * 6.2832 = 9424.78 radians per minute
- Divide by 60: 9424.78 / 60 = 157.08 rad/sec
- Convert 1200 rpm:
- 1500 * 2π = 7549.56 radians per minute
- Divide by 60: 7549.56 / 60 = 125.83 rad/sec
- Convert 2000 rpm:
- 2000 * 2π = 12566.37 radians per minute
- Divide by 60: 12566.37 / 60 = 209.44 rad/sec

Conversion Definitions
rpm
Revolutions per minute (rpm) measures how many complete turns an object makes in one minute. It is used to describe rotational speeds of engines, turbines, and other rotating equipment, indicating how fast something spins.
rad
Rad, short for radians, is a unit of angular measurement. One radian equals the angle at the center of a circle that subtends an arc equal in length to the radius. Radians are used in mathematics and physics to measure angles and rotational quantities.
Conversion FAQs
Why is multiplying rpm by 2π divided by 60 necessary?
This operation converts revolutions per minute into radians per second, because each revolution equals 2π radians, and there are 60 seconds in a minute. The multiplication accounts for radians per revolution, and division adjusts for time units, resulting in radians/sec.
Can I use the same formula for different rpm values?
Yes, the same formula applies to any rpm value: radians/sec = rpm * (2π) / 60. Just replace rpm with your number. This formula provides a consistent way to convert rotational speed units from revolutions per minute to radians per second.
What is the significance of converting rpm to rad/sec?
Converting rpm to rad/sec is vital for physics and engineering calculations involving angular velocity, torque, and rotational dynamics. Radians/sec are standard in equations describing rotational motion, making this conversion necessary for precise analysis.
