The full word for "ohms" is
"ohm" (singular) or
"ohms" (plural), and it is named after the German physicist
Georg Simon Ohm. He is famous for formulating
Ohm's Law, which relates voltage, current, and resistance in an electrical circuit. The unit "ohm" measures electrical resistance.
So, when you hear "1 ohm," it means the amount of resistance in a circuit that allows 1 ampere of current to flow when 1 volt of electrical pressure is applied.
