A measurement of molten ardite in millibuckets.

Millibucket is a unit of measurement often deployed for liquids in Minecraft. The millibucket measurement is often abbreviated to mB and stands for 1/1000th of a bucket of liquid, making Buckets the standard of which this measurement is based on. Every bucket of liquid contains exactly 1000mB or 1B of liquid. The prefix scheme comes from the Metric system and is rarely used with Minecraft excluding mB.
