# RMS (Root Mean Square) Velocity Calculator

Posted by Dinesh onOnline calculator tool helps you to find or calculate **Root Mean Square (RMS) Velocity** of Gas by using molecular weight, temperature values.

## Calculate RMS Velocity of Gas

### Formula:

c_{rms} = ?(3×R×T)/M

where,

R = Universal gas constant : [8.3145 (kg m^{2}/sec^{2})/K mol]

T = Absolute temperature

M = Molecular weight of the gas

rms - Root Mean Square
