Enter the milliamps and the time (hours) into the Calculator. The calculator will evaluate the Milliamps Per Hour. 

Milliamps Per Hour Formula

mah = ma/t


  • mah is the Milliamps Per Hour (milliamp/hr)
  • ma is the milliamps
  • t is the time (hours)

To calculate Milliamps Per Hour, divide the total milliamps by the time in hours.
