How do you convert decimal to hexadecimal

Divide the decimal number by 16.   Treat the division as an integer division.  Write down the remainder (in hexadecimal).

Divide the result again by 16.  Treat the division as an integer division.  

Repeat step 2 and 3 until result is 0.

The hex value is the digit sequence of the remainders from the last to first.

IMC is typically compared to RMC, but regarding weight it lies between RMC and EMT, or electrical metallic conduit.

EMT is commonly used for branch circuit wiring in homes (where the wiring runs are exposed) and in commercial buildings. EMT is never threaded and is not designed for strong connections like IMC and RMC.
