This article will show how to convert voltage measurement units from nanovolts (nV) to gigavolts (GV). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Volt, Nanovolt, and Gigavolt
Let’s get started by understanding the key definitions of Volt (V)
, Nanovolt (nV)
, and Gigavolt (GV)
. 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.
What is Gigavolt (GV)?
A gigavolt (GV) is a unit of electrical potential equal to one billion volts (1,000,000,000 V
). This measurement is used in applications involving extreme voltage levels that standard voltage units cannot effectively represent.

nV to GV 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)
while the giga-
represents a multiplier of 109 (1,000,000,000)
.
So, to convert from nanovolts to gigavolts, divide the number of nanovolts (V(nV)
) by 1018
or 1,000,000,000,000,000,000
.
V(GV) = V(nV) ÷ 1018 = V(nV) ÷ 1,000,000,000,000,000,000
Or remember the nV-to-GV
conversion factor: 1 nV = 10-18 = 0.000000000000000001 GV

Examples
Now, let's look at an example that illustrates the calculations required to convert from nanovolts to gigavolts (nV to GV).
Example: High-Energy Particle Research
Physicists working with nuclear reactions measure low-energy variations in nanovolts, but energy outputs must be expressed in gigavolts for accurate scaling in experiments.
If a nuclear experiment detects 4,200,000,000,000,000 nanovolts
, how many gigavolts is that for modeling reaction energy levels?
Solution
Since 1 gigavolts (GV) = 1018 = 1,000,000,000,000,000,000 nanovolts (nV)
, we can convert 4,200,000,000,000,000,000 (4.2 × 1018) nV
to gigavolts by using the following formula:
Therefore, the 4,200,000,000,000,000,000 nV
output voltage of the experiment is equivalent to 4.2 GV
.

FAQs
Is 1 nanovolt or 1 gigavolt larger?
A gigavolt (GV) is a quintillion times bigger than a nanovolt (nV). Here are the relationships between the units:
1 GV = 1018 = 1,000,000,000,000,000,000 nV
1 nV = 10-18 = 1 ÷ 1,000,000,000,000,000,000 = 0.000000000000000001 GV
