Mathcad 15 - Preferred units in results?

I am using Mathcad 15 for a course in Quantum Chemistry. Is there a way to set default units so that they match those commonly accepted in the dicipline?

For instance, when I calculate wavenumber, my result is in m^-1 rather than the commonly accepted cm^-1, and frequency is in s^-1 rather than Hz.

Thanks.

Best Regads,

Matthew

Further to Valerys post, which is correct.

Follow his instructions and select the custom option. Double click length which is found in the top box (base dimensions) and change meter to centimeter. For frequency, click the insert button on the derived unit box and choose frequency and then select your desired unit, Hz.

Thank you both for the replies. Indeed, the instructions got me most of the way to the answer. They produce "properly formatted" results that display frequency as Hz. To get the "accepted" display format for wavenumber, i.e., cm^-1, I needed to turn off "Format Units" as a global "Format Result" option.

Thanks once again.

Best Regards,

Matthew
