1 milligram is 0 st. One milligram is exactly 1.57473044418e-7 stone.

One milligram is 1.5747 × 10^-7 stone. To convert milligrams to stone, multiply by 1.5747 × 10^-7; to go the other way, divide by 1.5747 × 10^-7 or multiply by 6.3503 × 10^+6. The factor is exact rather than rounded: it follows from NIST Handbook 44. One thousandth of a gram, and exactly 1,000 micrograms.
