Created by

This article will show how to convert voltage measurement units from microvolts (µV) 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, Microvolt, and Nanovolt

Let’s get started by understanding the key definitions of Microvolt (µV), Nanovolt (nV), and Volt (V). 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 million microvolts, or 106 µV, or 1,000,000 µV.

What is Microvolt (µV)?

A microvolt (µV) is a unit of electrical potential equal to one-millionth (1/1,000,000) of a volt (0.000001 V). It is commonly used in applications requiring high-precision voltage measurements, such as biomedical sensors (e.g., EEG and ECG devices), seismic monitoring, and radio signal detection, where extremely small electrical signals must be accurately captured and analyzed.

Its fine resolution makes it essential for systems sensitive to even the slightest voltage variations.

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.

µV 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 micro- prefix in the International System of Units (SI) represents a multiplier of 10-6 (0.000001) while the nano- represents a multiplier of 10-9 (0.000000001).

So, to convert from microvolts to nanovolts, multiply the number of microvolts (V(µV)) by 1,000.

V(nV) = V(µV) × 103 = V(µV) × 1,000

$$\text{V}_\text{(nV)} = \text{V}_\text{(µV)} \times 1{,}000$$

Or remember the µV-to-nV conversion factor: 1 µV = 103 = 1,000 nV

Examples

Now, let's look at an example that illustrates the calculations required to convert from microvolts to nanovolts (µV to nV).

Example: Semiconductor Noise Measurement

In semiconductor devices, accurately measuring noise is crucial because even minor voltage changes can significantly affect performance. By converting data from microvolts to nanovolts, we can detect subtle variations in noise that are vital for optimizing electronic performance and ensuring precision in high-performance semiconductor devices.

For example, if a semiconductor device has a noise level of 30 µV, converting this measurement to nanovolts is essential for better analysis and calibration.

Solution

Since 1 microvolts (µV) = 1,000 nanovolts (nV), we can convert 30 µV to nanovolts by using the following formula:

$$\text{V}_\text{(nV)} = \text{V}_\text{(µV)} \times 1{,}000$$
$$\text{V}_\text{(nV)} = 30 \times 1{,}000 = \boxed{30{,}000 \text{ nV}}$$

Therefore, the 30 µV output voltage of the sensor is equivalent to 30,000 nV.

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

  1. Enter the value in microvolts – For this example, enter 30 into the From box.
  2. View the result – The converter instantly calculates and displays the equivalent value in nanovolts: 30,000 nV.

FAQs

Is 1 nanovolt or 1 microvolt larger?

A microvolt (µV) is a thousand times bigger than a nanovolt (nV). Here are the relationships between the units:

  • 1 µV = 103 = 1,000 nV
  • 1 µV = 10-3 = 1 ÷ 1,000 = 0.001 nV

How to convert from microvolts to nanovolts?

To convert voltage from microvolts (µV) to nanovolts (nV), follow these simple steps:

  • Write down the voltage value in microvolts (µV).
  • Multiply it by the value of the µV-to-nV conversion factor: 103 or 1,000.
  • The result of the multiplication is the value of the voltage in nanovolts (nV).

Why do I need to convert from microvolts to nanovolts?

Converting microvolts (µV) to nanovolts (nV) is essential for analyzing small electrical signals with high precision. In high-precision electronics and sensor measurements, even minor voltage fluctuations matter.

Using nanovolts clarifies data and captures every detail accurately, as 1 µV equals 1,000 nV. This conversion simplifies calculations, enhances readability, and improves compatibility with high-precision equipment, minimizing computational errors and enabling effective monitoring of minute voltage variations.

You now know how to convert voltage from microvolts (µV) to nanovolts (nV). You can quickly use our calculator to convert between the voltage measurement units to save time for future calculations.
