Case sensitive symbol for centimeters squared

If the c/s symbol for area in meters squared (m2) is 'ar' and the c/s symbol for the prefix centi is 'c', is the correct c/s symbol for centimeters squared 'car' or 'cm2'? The latter is seen in the definition unit for other measurements in the UCUM, such as the Poise and Stokes.

Let's review:

  • 1 ar = 100 m2
  • 1 car ("centi are") = 1 m2
  • 1 m = 100 cm
  • 1 m2 = 10,000 cm2 (square centi-meter)

Be careful, the exponent raises the entire unit (cm) to the given power, not just the unit atom (m). So 1 cm2 is one square centi-meter, not a centi of a square-meter.

Did I get anything wrong or misunderstand anything?
