Specific heat (CP) is defined as the ratio of heat required to raise the temperature of a given mass of any substance one degree to the same mass of a standard substance one degree. Which units are typical for CP?

Explanation:
Specific heat capacity tells you how much energy is needed to raise the temperature of a given mass by one degree. That means the units must be energy per mass per temperature. In SI this is joules per kilogram per kelvin (J/(kg·K)). In English engineering units it’s Btu per pound per degree Fahrenheit (Btu/(lb·°F)). The other options don’t fit: W/(m·K) is thermal conductivity, Pa is pressure, and Celsius per gram isn’t a standard energy–per–mass–per–temperature unit.
