What are the units to Q=MC∆T?

The reason I ask is I find one website that was it's Celsius and grams.

Another website said Kelvin and kilograms.

    Any temperature CHANGE is the same when stated in Celsius or Kelvin so it make no difference which is used.

    The key to using g or Kg is what units the C is given in. You can use g or Kg but you may have to convert the C constant by multiplying by 1000 or dividing by 1000 if the units are not the same. Eg if C = 2.6 J/kg∙°C then if you use kg the conversion is not required as they are in the correct units , how ever if you use g then the conversion is per kg so you need to multiply by 1,000 and change your g in to kg.
