This article will show how to convert voltage measurement units from volts (V) to nanovolts (nV). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Volt and Nanovolt
Let’s get started by understanding the key definitions of Volt (V)
and Nanovolt (nV)
. Understanding these terms will allow you to perform conversions confidently.
What is Volt (V)?
A volt (V
) is the SI (International System of Units) unit of electric potential and voltage. It measures the difference in electric energy between two points in a circuit. One volt means one ampere of current uses one watt of power.[1]
According to SI prefixes[2], which are based on powers of 10, a volt (1 V
) is equivalent to one billion nanovolts, or 109 nV
, or 1,000,000,000 nV
.

What is Nanovolt (nV)?
A nanovolt (nV) is a unit of electrical potential equal to one-billionth (1/1,000,000,000
) of a volt (10-9 V
). It is primarily used in high-precision electrical measurements, such as scientific instrumentation, quantum electronics, and sensitive signal detection, where extremely small voltage variations must be accurately captured and analyzed.

Its ultra-small scale makes it essential for applications requiring minimal interference and precise voltage control.
V to nV 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 volts to nanovolts, multiply the number of volts (V(V)
) by 1,000,000,000
.
V(nV) = V(V) × 109 = V(V) × 1,000,000,000
Or remember the V-to-nV
conversion factor: 1 V = 1,000,000,000 nV
Examples
Now, let's look at an example that illustrates the calculations required to convert from volts to nanovolts (V to nV).
Example: Analyzing Weak Neural Signals in Brain Research
In neuroscience research, scientists study electrical activity in the brain using high-precision electrodes. These electrodes detect tiny voltage signals, often measured in nanovolts (nV), to analyze neural patterns associated with cognition, motor functions, and medical conditions such as epilepsy.
A team is studying brain waves using a neural probe. The probe detects a voltage of 0.00000093 V
, a signal smaller than a speck of dust. To analyze it properly, they convert this value to nanovolts. Why? Because nanovolts let them see details like shifts in neuron communication or early signs of a seizure.
Solution
Since 1 volt (V) = 1,000,000,000 nanovolts (nV)
, we can convert 0.00000093 V
to nanovolts by using the following formula:
Therefore, the 0.00000093 V
output voltage of the scientific instrument is equivalent to 930 nV
.
To solve the problem with our calculator, follow the steps below:
- Enter the value in volts – For this example, enter
0.00000093
into theFrom
box. - View the result – The converter instantly calculates and displays the equivalent value in nanovolts:

FAQs
Is 1 volt or 1 nanovolt larger?
A volt (V) is a billion times bigger than a nanovolt (nV). Here are the relationships between the units:
1 V = 109 = 1,000,000,000 nV
1 nV = 10-9 = 1 ÷ 1,000,000,000 = 0.000000001 V

Why do I need to convert volts to nanovolts?
Think of it like detecting whispers in a noisy room. Nanovolts (nV) help capture ultra-small electrical signals that standard measurements might overlook. Here’s where it matters most:
- Neuroscience research relies on nanovolt precision to track brain activity. Without it, subtle neural signals could go undetected.
- Quantum sensors use nanovolt measurements to analyze microscopic energy shifts, which are crucial for advanced physics experiments.
- Space telescopes detect faint cosmic signals in nanovolts, helping astronomers study distant galaxies and black holes.
