A UK long ton equals 1,016,047,000 milligrams, making a milligram roughly one billionth of a long ton. This conversion is essentially never needed in practice — milligram precision is for labs and pharmaceuticals, while long tons are for bulk shipping and historical cargo. The only potential crossover is in UK regulatory documentation for large batches.
