120v vs 120 v

Both "120v" and "120 v" are commonly used to refer to a voltage of 120 volts. The difference lies in the formatting, where one version has a space between the number and the unit symbol, while the other does not. Both formats are acceptable, but the version without a space is more common in technical contexts.
