Nanoampere to Ampere Converter

This article will show how to convert electric current measurement units from nanoamperes (nA) to Amperes (A). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.

Definitions of Ampere and Nanoampere

Let’s get started by understanding the key definitions of Ampere (A) 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.

Ampere Definition and Illustration — What is Ampere? The definition and illustration.

According to SI prefixes^[2], which are based on powers of 10, an ampere (1 A) is equivalent to one billion nanoamperes (10⁹ nA or 1,000,000,000 nA).

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.

nA to A 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 nano- prefix in the International System of Units (SI) represents a multiplier of 10^-9 (0.000000001). So, to convert from nanoamps to amps, divide the number of nanoamps (I_(nA)) by 10⁹ (1,000,000,000).

I_(A) = I_(nA) ÷ 10⁹ = I_(nA) ÷ 1,000,000,000

\text{I}_\text{(A)} = \frac{\text{I}_\text{(nA)}}{1{,}000{,}000{,}000}

Or remember the nA-to-A conversion factor: 1 A = 10^-9 = 0.000000001 A

Nanoamperes (nA) to amperes (A) conversion table

Examples

Now, let's look at an example that illustrates the calculations required to convert from nanoamperes to amperes (nA to A).

Example: Laboratory Instrumentation Calibration

In a research lab, instruments may measure ultra-low currents in nanoamperes during experiments. Converting these currents to amperes provides consistency when recording and sharing data.

If an instrument records 1,500 nA, how many amperes is that? You need it to confirm that measurement devices are operating correctly.

Solution

Since 1 ampere (A) = 10⁹ = 1,000,000,000 nanoamperes (nA), we can convert 1,500 nA to amperes by using the following formula:

$$\text{I}_\text{(A)} = \frac{\text{I}_\text{(nA)}}{1{,}000{,}000{,}000}$$

$$\text{I}_\text{(A)} = \frac{1{,}500}{1{,}000{,}000{,}000} = 1.5 \times 10^{-6} = \boxed{0.0000015 \text{ A}}$$

Therefore, the 1,500 nA electric current is equivalent to 0.0000015 A.

To solve the problem with our calculator, follow the steps below:

Enter the value in nanoamperes: For this example, enter 1,500 into the From box.
View the result: The converter instantly calculates and displays the equivalent value in amperes: 0.0000015 A.

FAQs

Is 1 nanoampere or 1 ampere larger?

An ampere (A) is a billion times bigger than a nanoampere (nA). Here are the relationships between the units:

1 A = 10⁹ = 1,000,000,000 nA
1 nA = 10^-9 = 1 ÷ 1,000,000,000 = 0.000000001 A

How to convert from nanoamperes to amperes?

To convert electric current from nanoamperes (nA) to amperes (A), follow these simple steps:

Write down the electric current value in nanoamperes (nA).
Multiply it by the value of a nA-to-A conversion factor: 10^-9 or 0.000000001.
The result of multiplication is the value of the electric current in amperes (A).

Why do I need to convert nanoamperes to amperes?

Converting nanoamperes to amperes simplifies calculations by reducing long strings of zeros and decimals. It ensures that measurements fit the standard SI unit used in many technical specifications.

It also makes comparisons easier when designing and testing circuits, as most datasheets and simulation tools list current values in amperes.

You now know how to convert electric current from nanoamperes (nA) to amperes (A). You can quickly use our calculator to convert between the electric current measurement units to save time for future calculations.
