The “m” in “mA” is always lower case and the “A” is always upper case. mAh – Is a measure of charge. 1 mAh is the amount of charge transferred by moving 1 mA of current for a period of one hour. It would be how much water has flowed through the pipe over a period of time.
How do you convert mA to mAh?
Convert amps (A) and hours (h) to mAh (milliampere-hours) The formula is (A)*(h)*1000 =(mAh). For example, if you have a current of 3 A running for 5 hours, the number of mAh is 3A*5h*1000 = 15000mAh.

What is mA in battery?
A milliampere hour (mAh) is 1000th of an ampere hour ( Ah ). Both measures are commonly used to describe the energy charge that a battery will hold and how long a device will run before the battery needs recharging.
Is amps the same as mAh?
MilliAmp hour means how much current a battery will discharge over a period of one hour.A 1700 will sustain a 1700 mAh (1.7 amp) draw for one hour. 1000 mAh is equal to a 1 Amp Hour (AH) rating.
How do you convert mA to physics?
To convert a milliampere measurement to an ampere measurement, divide the electric current by the conversion ratio. The electric current in amperes is equal to the milliamperes divided by 1,000.

How many mAh is A 9V battery?
Technical Specifications Of The 9V Battery
| 9V Battery Nominal Voltage: | 9 Volts |
|---|---|
| Capacity (Alkaline) ≈ | 550 mAh |
| Capacity (Carbon-Zinc) ≈ | 400 mAh |
| Capacity (Lithium Primary) ≈ | 1200 mAh |
| Capacity (NiMH) ≈ | 175-300mAh |
How many mAh is A AA battery?
For example AA alkaline batteries typically have a capacity rating of over 2,500 mAh and AA NiMH batteries have rated capacities of only 1,200 to 2,000 mAh. But when it comes to actually powering an electronic device like a digital camera, the NiMH batteries will often run the device for three or four times a long.
How many mAh is A 12 volt battery?
Assuming the unit is as efficient in producing 12 V as 3.7 volts then the mAh rating at 12 V would be 20000 * 3.7/12 = 6167 mAh.
What does 2000amh mean?
mAh is the capacity rating of the battery. Small batteries like this one are rated in milli-amperes or thousandths of an ampere. A 2000mAh rating means that the battery can supply 2000mA (or 2 amps) of current for the time period of the rating. A higher number means a battery with a higher capacity, and vice-versa.
Is higher milliamps better?
In general, the more mAh and the longer the battery capacity or battery life. A higher number means that the battery can store more energy, so it has a higher capacity. Of course, this also means longer battery life for a given usage.
How many mAh is 30 amps?
amps to milliamps metric conversion table
| amps to milliamps metric conversion table | ||
|---|---|---|
| 0.01 A = 10 mA | 0.1 A = 100 mA | 31 A = 31000 mA |
| 0.02 A = 20 mA | 0.2 A = 200 mA | 32 A = 32000 mA |
| 0.03 A = 30 mA | 0.3 A = 300 mA | 33 A = 33000 mA |
| 0.04 A = 40 mA | 0.4 A = 400 mA | 34 A = 34000 mA |
What is mAh in a battery?
Simply put, Ampere-Hour (mAh) is a measure of electric charge, which represents the capacity of a battery, while Watt Hour (Wh) is a measure of electric energy. Watt-Hour = Ampere-Hour x Voltage. A battery of 10400mAh means this battery can provide a total charge of 10400mAh at a specific voltage.
Are amps and amp-hours the same?
In the measurement of electricity, amps are a unit of electrical current; amp-hours are units of current storage capacity. For a given voltage, the more power an electrical circuit consumes, the more current flows through it.
How many mA is 2 amps?
2000 mA
Ampere to Milliampere Conversion Table
| Ampere [A] | Milliampere [mA] |
|---|---|
| 0.01 A | 10 mA |
| 0.1 A | 100 mA |
| 1 A | 1000 mA |
| 2 A | 2000 mA |
Is 2000mA the same as 2 amps?
2000mA is 2A. There is no way to get 2.1A from it at the rated specs. And you can’t get 1A and 2A from it either, as that would require 3A total.
Do you have to convert mA to a?
Converting mA to voltage is common in HVAC when working with pressure transducers. Terminology to keep in mind includes: 1 mA = 0.001 AMP (short for amperes)
E stands for volts, I stands for amps, and R stands for resistance.
| If your control circuit is using a 250Ω resistor: | ||
|---|---|---|
| mA | Amps x Resistance | Volts |
| 5 | 0.005 x 250Ω | 1.25 |
How do you calculate milliamps per hour?
Insert Watts-hour (Wh) and voltage (V) and click on Calculate to obtain milliamp-hours (mAh). Formula is (Wh)*1000/(V) =(mAh). For example, if you have a 1.5Wh battery rated at 5V, the power is 1.5Wh * 1000 / 5V = 300mAh.
What’s the difference between amp-hours and milliamp hours?
One ampere-hour (or amp-hour or Ah) is a current of one ampere flowing for one hour. The amount of charge transferred in that hour is 3,600 coulombs (ampere-seconds). A milliampere-hour (mAh or milliamp-hour) is a thousandth of an amp-hour.
How do you find the mAh of a battery?
Calculate the battery’s milliamp-hour rating by multiplying the number of hours recorded on the stopwatch by the initial current reading on the meter. For example, if the meter initially read 90 milliamps and the stopwatch is at 10 hours, the milliamp-hour rating is 90 * 10 or 900 mAh.
