Approximately 50,802,350 milligrams. One long hundredweight is about 50,802.35 grams, and each gram is 1,000 milligrams.

Is this conversion ever needed?

Never in practice. The milligram and long hundredweight serve completely different domains - pharmacy and British commodity trading respectively.

Why is the number approximate?

Because the long hundredweight is defined in pounds (avoirdupois system) while the milligram is metric. The cross-system conversion introduces a non-terminating decimal.

Non-Frequently Asked Questions About Milligrams to Hundredweights (UK)

Questions nobody should ask - but someone did.

At 325 milligrams per tablet, one long hundredweight (50,802,350 mg) would require about 156,315 aspirin tablets. Stacked, they would form a tower roughly 78 meters tall - about the height of a 20-story building. That is a lot of headaches.
No pharmacy stocks a hundredweight of any single medication. Even a busy hospital pharmacy handles perhaps 10-20 kilograms of any given drug per year. A hundredweight (50.8 kg) of most drugs would be a multi-year supply for an entire hospital wing.
50 million milligrams is just 50.8 kilograms - about the weight of a person. The number sounds dramatic only because milligrams are small. Expressing a coal sack in milligrams does not make coal more interesting; it just makes the number larger.
