How to convert mAh to Wh  How to convert milliamp-hour (mAh) to
watt-hour (Wh).  milliamper-hour to watt-hour calculation  The
energy E(Wh) in watt-hours is equal to the electric charge
Q(mAh) in milliampere-hour times the voltage V(V) in volts (V)
divided by 1000:   So watt-hour is equal to milliamp-hour times
volts divided by 1000:  watt-hours = milliampere-hours × volts /
1000   Wh = mAh × V / 1000   Find the energy in watt-hours when
the electric charge is 300 milliampere-hour and the voltage is 5
volts.  The energy E is equal to 300 milliamp-hour times 5 volts
divided by 1000:  E = 300mAh × 5V / 1000 = 1.5Wh   How to
convert Wh to mAh   See also  Write how to improve this page
