Revolutions per minute to radians per second
Type a value in rpm to get it in rad/s instantly.
1,047.083rad/s
That's 4.8× as strong as separating plasma, while a hard spin-down is 1.26× higher. Your sample effectively weighs 9,503 times its own weight.
What it means
How hard is that spin?
Radii are to the bottom of the tube, where the force is highest. A protocol written for the middle of the tube will give a slightly lower figure.
The math
How to convert rpm to rad/s
Both describe the same spin: rad/s = rpm × 2π ÷ 60. The force follows from the square of either one.
Example: 10,000 rpm = 1,047.08 rad/s.
The table below is for Microcentrifuge (8.5 cm).

Revolutions per minute (rpm)
What the machine’s dial reads. Meaningless without the rotor size.
Radians per second (rad/s)
The angular velocity, as the physics is actually written.
