### Convert mAh (milliamp hours) to Time in Hours

https://www.convert-formula.com/mah-hours
The formula is (mAh)/ (Amps*1000) = (hours). For example, if you have a 3000 mAh battery that runs at 0.2 Amps (0.2Amps = 200mA), then the time that the battery will last for is (3000)/ (0.2*1000) = (3000)/ (200)= 15 Hours. If instead of the current you have voltage and watts, then the formula is (mAh*Volts)/ (Watts*1000) = (hours).

### mAh to Watt-hours (Wh) conversion calculator

https://www.rapidtables.com/calc/electric/mah-to-wh-calculator.html
milliamp-hours to watt-hours calculation. The energy E (Wh) in watt-hours is equal to the electric charge Q (mAh) in milliamp-hours times the voltage V (V) in volts (V) divided by 1000: E (Wh) = Q (mAh) × V (V) / 1000. So watt-hours is equal to milliamp-hours times volts divided by 1000: watt-hours = milliamp-hours × volts / 1000. or. Wh = mAh × V / 1000

### mAh Battery Life Calculator

https://ncalculators.com/electrical/battery-life-calculator.htm
mAh Battery Life Calculator is an online tool used in electrical engineering to precisely calculate battery life. Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh. Ampere is an electrical unit used to measure the current flow towards the load.

Battery Life Calculator. This battery life calculator estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used.

### Hours Calculator

7:15 is 7.0 hours plus 15 minutes. You'll need to convert the minutes part to hours. 15 minutes times 1 hour per 60 minutes will make the conversion to hours and minutes will cancel out. 15 min × (1 hr / 60 min) = (15/60) hr = 0.25 hr. Adding the 0.25 to the 7.0 our total is 7.0 + 0.25 = 7.25 hours.
