How many millirems are in one rem?

Explanation:
Understanding unit prefixes and dose units: rem vs millirem. “Milli” means one thousandth, so to express the same dose in the smaller unit you multiply by 1000. The rem is a unit of dose, and millirem is just that dose in the smaller unit. Therefore, 1 rem equals 1000 millirems. For example, 0.5 rem is 500 millirem. The scaling shows why the other numbers wouldn’t match the same dose expressed in millirems.
