About Converting Centigrams to Megagrams
Weight conversions between Centigram and Megagram 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: Centigram is 0.01 gram units, and megagram is 1000000 gram units.
Formula
megagrams = centigrams × 1e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram equals 0.00001 base units, and 1 megagram equals 1000 base units, so dividing one by the other gives the direct centigram-to-megagram factor of 1e-8.
Simple example
1 cg × 1e-8 = 1e-8 Mg
1 centigram = 1e-8 megagrams.
Real-world example
50 cg × 1e-8 = 5e-7 Mg
50 centigrams = 5e-7 megagrams.
