How to convert Exameter to Didot point

Conversion factor and calculation steps from Exameter (Em) to Didot point (dd).

Conversion logic

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 Em = 1.00000000e18 m

1 dd = 0.000376065 m

1 Em × 1.00000000e18 = 1.00000000e18 m

1.00000000e18 m ÷ 0.000376065 = 2.65911478e21 dd
