Unit conversion problem (kg*m^2/s^3*rad -> W)

[norbre-hu]

Hi,
We have a simple motor power calculation:

n = 1500 rpm = 25 1/s
ω = n·360 ° = 25 1/s·360 ° = 157.08 rad/s
T = 1 Nm
P = T·ω = 1 Nm·157.08 rad/s = 157.08 kg·m2/s3·rad

The problem is that, if we would like to see the P in unit W, it occurs error.
P = T*ω|W
The calculated units "kg·m^2/s^3·rad" are inconsistent with the target units "W".

I guess kg·m^2/s^3·rad has to be W:
kg*m^2/s^2 = N
m/s = velocity
N * m/s = W

How can we solve this?
Thank you

Hi this is because the radians. In Calcpad they cannot fall off automatically. So, multiply the last formula to rad^-1.
