Why convert ESU of charge to nanocoulombs?
-
Conversion helps translate theoretical and legacy charge data in CGS units into nanocoulombs, an SI unit commonly used for small charge measurements in practical and experimental contexts.
-
What is the conversion factor between ESU and nanocoulomb?
-
1 ESU of charge equals 0.3335640952 nanocoulombs.
