How can I convert a cord to a plug?

You can't but you can install a plug on the end of a cord. Just go purchase one and install it. Very simple to do. Black wire goes to copper screw, white wire goes to silver screw, and ground or green wire goes to ground screw. It both wires are brown then connect the wire with the ridges on the outside of the wire to the silver screw as it is the neutral. The wire that is smooth is the black hot wire which connects to the copper screw.

Answer for UK, Europe and countries running a 50 Hz supply service.It all depends on which connection you are using. Alternating Current (AC) or Direct Current (DC). In AC there are generally two modes of transmission. Single Phase or Three Phase. In case you don't have 3-phase connection just combine yellow and green.According to Standard, Green is for the Earth Wire and Red is for the Live wire. Blue or Black is for the Neutral Wire. So best option is to combine the Yellow and Green.
