About Converting Solar mass to Drams
Weight conversions between Solar mass and Dram come up constantly in everyday commerce, shipping, and cooking, since US packaging is usually labeled in pounds while most of the rest of the world uses kilograms. Specifically: Solar mass is used in astronomy, and an avoirdupois dram is 1/16 ounce.
Formula
drams = solar mass × 1.122259e+33
This factor comes from each unit's defined relationship to the category's base unit: 1 solar mass equals 1.98847e+30 base units, and 1 dram equals 0.00177184519531 base units, so dividing one by the other gives the direct solar mass-to-dram factor of 1.122259e+33.
Simple example
1 Msun × 1.122259e+33 = 1.122259e+33 dr
1 solar mass = 1.122259e+33 drams.
Real-world example
50 Msun × 1.122259e+33 = 5.611297e+34 dr
50 solar mass = 5.611297e+34 drams.
