Megameter to Light-day
Megameter (Mm)
Light-day (ld)
How it is calculated
Each unit is defined via the base unit (meter (m)). The value is first converted to the base unit, then to the selected unit.
1 Mm = 1000000 m
1 ld = 2.59020684e13 m
1 Mm × 1000000 = 1000000 m
1000000 m ÷ 2.59020684e13 = 3.86069555e-8 ld
