These numbers have no direct correlation to electric motors.  Althought some of the electric motor manufacturers have tried to equate their motors to equivalent glow sized motors so glow pilots going to electric can come over more easily.

Note that for a given size, glow planes tend to be heavier as they need a lot of reinforcement to stand up to the vibration of the motor.  Electric motors don't vibrate like that so we don't have to reinforce for it.

Also glow planes have to be fuel proofed where electrics don't.

When sizing motors for planes, use the watts/poung guide lines as discussed in this e-book.
