Intradermal is between layers of the skin. Subcutaneous is beneath the skin.
An intradermal injection is made into the middle layers of the skin.
Subcutaneous (subQ) injections are typically given in the fatty tissue layer between the skin and the muscle, usually in the abdomen, thigh, or upper outer arm. Make sure to rotate injection sites to prevent irritation or tissue damage.
The injection rate is the number of injections. The injection pressure is the pressure the injection is under.

Subcutaneous administration involves injecting the solution into the subcutaneous tissue beneath the layers of skin (i.e. the space between the dermis and the muscle).
For humans, it's best to give a subQ injection at 90 to 45 degrees. Ninety-degrees is best if you have tented 2 inches of skin. Forty-five degrees only if you have tented one inch of skin.For livestock though, it is best to give subQ shots at a 30 to 45 degree angle relative to the surface of the body after tenting the skin with thumb and forefingers. This is especially true when you have to give a SubQ shot to livestock like horses, cattle, sheep, and goats.A subcutaneous injection can be given at either a 90 or a 45 degree angle.
Fuel injection vs carburation.
Intramuscular broken down is intra- (which means into or inside) and muscular (which is the muscle) so it is a shot or injection into the muscle while subcutaneous (the cutaneous layer is your skin) is where the injection goes into the skin but not deep enough to penetrate muscle.
