Milliamps to Amps Guide: How to Convert Milliamps to Amps
Converting milliamps to amps or amps to milliamps is pretty simple. While most people think it is only an electrician affair, understanding these electrical concepts and conversions will save you a lot of money and time, particularly when choosing energy-efficient electrical appliances. To convert these units accurately, you must understand basic definitions such as the current, amperes, and milliamperes.
Additionally, you must understand the formulas for each type of conversion. For instance, 1 ampere equals 1,000 milliamperes while 1 milliampere equals 0.001 ampere (1A = 1,000mA, 1mA = 0.001A).
In this article, we will guide you on how to convert amps to milliamps and milliamps to amps. We shall provide easy-to-understand formulas for each type of conversion. Keep reading!
What is Milliampere (mA)?
Milliampere is symbolized as mA. It is a unit for measuring an electric current. Also, it is a sub-unit of an ampere. It represents one-thousandth ampere (1 mA = 0.001 A).
A milliampere is equivalent to 1/1000 of one ampere. An electrical current is equal to a flow of one coulomb per second.
Milliampere (mA) is commonly applied in instances where electric currents are relatively minimal. An electric current flowing to charge a smartphone through a charger is measured in milliamperes. Computing using milliamperes as a measuring unit gives you precision when calculating lower electricity currents. The measuring unit (mA) is commonly indicated on circuits, household appliances, and modern electronic devices.
What is Ampere(A)?
An ampere, also identified as ‘amp’ is abbreviated as ‘A’. For example, you can write one ampere as 1A. It is a base unit under the International System of Units (SI) for measuring the strength of an electric current.
An ampere was redefined in 2019 as an electric current that is steady and consistent with the flow of 1/(1.602 176 634 × 10-19) elementary charges/ second.
The bigger the ampere value, the higher the current intensity. Similarly, the lower the ampere unit means a weak electric current intensity. In most cases, amperes are used to explain higher electric currents, in larger applications such as washing machines, refrigerators, and some industrial machines.
Ampere and Ohm's Law
Ohm's law states that a current between two points in a conductor is relative to the voltage and it is inversely proportionate to the resistance.
Ohm’s law is expressed using this formula: I = V / R
The current, also known as amps, is equivalent to the voltage or volts and the resistance (ohms).
How Many Milliamps Are in an Amp?
A milliampere(mA) is equivalent to 1/1000 of the ampere(A). In simpler terms, 1,000 milliamperes is equivalent to one ampere. Alternatively, 1 amp is equal to 1000 milliamps.
Mathematically, if you want to convert Amps to Milliamps, you will multiply the amperes by 1,000.
How to Convert Milliamps to Amps (mA to A)
To convert milliamps to amps, divide the number of milliamperes by 1000.
Method: A= mA ÷ 1000
Example: Convert 5000mA to Ampere
5000mA=5000mA ÷ 1000=5A
Example: Convert 10,000mA to A
10,000mA=10,000mA ÷ 1000= 10A
As described above, milliamps describe smaller electric currents such as in smartphones, laptops, and small appliances.
Ampere defines larger electrical currents, especially in bigger appliances such as refrigerators, freezers, washing machines, and ACs among others. The conversion of mA to A allows you to practically understand electric currents while ensuring consistency as you compare various appliances or machines with different electric units.
How to Convert Amps to Milliamps(A to mA)
Amperes are commonly used in most power systems. However, there are a few scenarios where you need to convert amps to milliamps, especially if you are dealing with different values. The conversion of a mix of big and small currents ensures there is consistency and helps in simplifying the comparisons.
Similar to converting milliamps to amps, you can convert amps to milliamps. Therefore, one amp is equivalent to 1,000 milliamps. The conversion formula for Amps to milliamps is as follows:
Method: mA = A × 1000 or Milliamps (mA) = Amps (A) x 1,000
Example: Convert 3A to mA
3A= 3A x 1000=3000mA
Example: Convert 5.5A to mA
5.5A=5.5A x 1000=5,500 mA
Example: Convert the Renogy 40 Amps Solar Charge controller to milliamps.
40A= 40A x 1000=40,000 mA

Frequently Asked Questions About Converting mA to A
1. Is 1000 Milliamps equivalent to 1 amp?
That’s right. One ampere is equivalent to 1000 milliamps. In other words, one milliamp is a thousandth of an Amps. Therefore, 1000 milliamps / 1000= 1 ampere.
2. How many amps are equivalent to 50 milliamperes?
A milliampere is one-thousandth of one amp. Therefore, you should divide the milliamps by 1000 to establish the ampere. Thus, 50 divided by 1000 is equal to 0.05 Amps.
3. What is the equivalent of 500 Milliamps in Amps?
The equivalent of 500 milliamps in Amps is 0.5. This is because one milliamp is equivalent to one-thousandth of one amp. You should divide mA by 1,000 to get the Amp value. In this case, 500 mA/1000 mA=0.5A.
4. What is the connection between Amps Watts and Volts?
When dealing with any electricity applications such as charge controllers or power stations, you will certainly come across these terms.
Amps- An amperage is a unit for calculating the sum of electrons moving from point A to B every second. A higher Amperage signifies more electricity moving through the circuit.
Watts- Wattage is the amount of energy a certain electric device uses. If the wattage is high, it means that the device consumes a high amount of electricity.
Volts- Voltage measures the pressure or force an electric current needs to travel through an electric wire. To better understand this correlation, apply this formulation: Watts = Amps × Volts.
