Mass of a sugar or extract needed to raise a wort to a target gravity, kg.
kg = (points_target − points_current) × V / pointsPerKgPerL. For "my pre-boil gravity is low, how much DME do I add?". Ignores the small volume the sugar itself adds.
kg = (points_target − points_current) × V / pointsPerKgPerL
