In physics, the word "heat" is used for a type of energy; so that would be the joule.

The SI unit for heat is the joule (J). Additionally, the calorie (cal) is a commonly used non-SI unit for heat, where 1 calorie is equivalent to 4.184 joules.
"SI unit" and "metric unit" basically means the same. The only metric system used nowadays is the SI. For a specific object, the heat capacity is measured in J/K. To compare different materials, it is of interest to specify the heat capacity PER KILOGRAM, so the units are J / (K times kg). It is also possible to specify heat capacity in J / (K times mole). This would also be SI units.
The unit for specific heat if Joules per kilogram per kelvin (Jkg-1K-1)Now kg and K are both already SI units for mass and temperature respectively. But the Joule is the unit of energy which is not an SI unit; it is a derived unit.Now energy= force x distance = Newtons x metersSo now we have Joules being equal to newton x meters. but the newton is also a derived unit for the quantity of forceForce = mass x acceleration = kg x ms-2Now we have everything in SI unit form:Joules = (force) x (distance) => From this we get:Joules = (kgms-2) x (m) = kgm2s-2Now specific heat = Jkg-1K-1 ; Substituting the values for Joules:Thus we arrive at specific heat = (kgm2s-2) x (kg-1) x (K-1)Expanding: m2s-2K-1 (the (kg) x (kg-1) cancel out each other.)
"si" stands for the International System of Units, which is the modern form of the metric system. It is based on seven base units, one of which is the meter for length.
In SI units: kJ/kmol

Seven metric base units make up the foundation of SI. And Specific combinations of SI base units yield derived units. That's why the differ.
a specific combination of base units with its own name
In SI units, temperature is measured in Kelvin (K), and when people record the "heat" (such as how warm a room is, etc.) they usually mean temperature. If you mean heat in the strict scientific sense, you're talking about a transfer of energy, and energy has SI units of Joules.
In SI, specific heat capacity is measured in joules per kilogram kelvin.
In SI, all forms of energy are measured in joules.
No, not all metric units are part of the International System of Units (SI). The SI is a coherent system of units derived from the metric system, but it is more specific and defined, and not all metric units are included in the SI.
