This article will show how to convert electric current measurement units from megaamperes (MA) to nanoamperes (nA). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Ampere, Megaampere, and Nanoampere
Let’s get started by understanding the key definitions of Ampere (A), Megaampere (MA), and Nanoampere (nA). Understanding these terms will allow you to perform conversions confidently.
What is Ampere?
The ampere (A) is the SI base unit of electric current, representing the amount of charge flowing through a conductor per second.[1] It is defined based on the elementary charge (e), where 1 A = 1 coulomb per second (C/s).
"Amp" is an informal abbreviation commonly used in everyday conversation and electrical contexts, though "A" remains the official SI unit symbol.
According to SI prefixes[2], which are based on powers of 10, an ampere (1 A) is equivalent to one millionth (1/1,000,000) of a megaampere (10-6 MA or 0.000001 MA).
What is a Megaampere?
A megaampere (MA) is a derived unit of electric current in the SI system equal to one million ampere (1,000,000 A).
It exists for extremes: simulating cosmic-scale energy bursts or probing physics frontiers. It’s a unit for specialists, not everyday tech, but it’s crucial for breakthroughs that could redefine how humanity harnesses power.
What is Nanoampere?
A nanoampere (nA) is a unit of electric current in the SI system equal to one billionth (1/1,000,000,000) of an ampere (10-9 A).
It represents an extremely small current level, commonly used in fields where precise measurements are necessary, such as semiconductor testing, quantum computing, nanotechnology research, and biomedical sensors, where minimal electric current variations must be accurately captured and analyzed.
MA to nA formula
Let’s take a closer look at the conversion formula so you can carry out these conversions independently, whether using a calculator or doing it manually with pencil and paper.
The mega- prefix in the International System of Units (SI) represents a multiplier of 106 (1,000,000) while the nano- represents a multiplier of 10-9 (0.000000001).
So, to convert from megaamps to nanoamps, multiply the number of megaamps (I(MA)) by 1015 (1,000,000,000,000,000).
I(nA) = I(MA) × 1015 = I(MA) × 1,000,000,000,000,000
Or remember the MA-to-nA conversion factor: 1 MA = 1015 = 1,000,000,000,000,000 nA

Examples
Now, let's look at an example that illustrates the calculations required to convert from megaamperes to nanoamperes (MA to nA).
Example: High-Energy Plasma Research Facility
A high-energy plasma research facility operates advanced containment chambers, where currents are measured in megaamperes. For precision monitoring and experimental calibration, scientists convert these large-scale measurements to nanoamperes to compare with detailed sensor outputs. This ensures accurate modeling of fine plasma behaviors.
If a plasma reactor operates at 2.21 MA, what is the current in nanoamperes? You need it to align large plasma flow data with ultra-sensitive instruments.
Solution
Since 1 megaampere (MA) = 1015 = 1,000,000,000,000,000 nanoamperes (nA), we can convert 2.21 MA to nanoamperes by using the following formula:
