If you're calculating RPM from wheel then the RPM to Linear Velocity formula is:
v = r × RPM × 0.10472
Where:
v: Linear velocity, in m/s
r: Radius, in m
RPM: Angular velocity, in RPM (Rounds per Minute)

If in case you're dealing with engine RPM then:

vehicle speed in miles/hour = (0.00595) * (RPM * r) / (R1 * R2)

where:
RPM = engine speed, in revolutions/minute
r = loaded tire radius (wheel center to pavement), in inches
R1 = transmission gear ratio
R2 = rear axle ratio
