    pi is a dimensionless number (just like 23.8) and has no unit - it is the ratio of circumference to diameter of a circle.In some circumstances you could argue pi is an angle with units of radian (pi radians = 180 degrees), but I think that would be 'unusual' and certainly pi is not a unit itself.
