# Physics - Unit Conversion

I am trying to calculate heat transfer between two objects. The units are as follows:

mass: grams

specific heat: cal/gm degree celsius

temperature: degree celcius

My numbers aren't working out and I know how to do the problem. So, what's the deal with the gm. Is that gram mass or another abbreviation for gram? Either way, gram mass for a solid or liquid is the same as grams??
