About Converting Megameters to Quettameters
Megameter and Quettameter both measure length. Specifically: Megameter is 1000000 meter units, and quettameter is 1e+30 meter units.
Formula
quettameters = megameters × 1e-24
This factor comes from each unit's defined relationship to the category's base unit: 1 megameter equals 1000000 base units, and 1 quettameter equals 1e+30 base units, so dividing one by the other gives the direct megameter-to-quettameter factor of 1e-24.
Simple example
1 Mm × 1e-24 = 1e-24 Qm
1 megameter = 1e-24 quettameters.
Real-world example
10 Mm × 1e-24 = 1e-23 Qm
10 megameters = 1e-23 quettameters.
