g/L\text{g/L}

gram per litre

Mass concentrationexact by definition

One gram of dissolved substance in one litre of solution, equal to 1000 mg/L and numerically identical to a kilogram per cubic metre. It is the unit for concentrated solutions — brines, feedstocks, culture media and anything strong enough that milligrams would be unwieldy.
