Microvolt to Volt Converter

This article will show how to convert voltage measurement units from microvolts (µV) to volts (V). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.

Definitions of Microvolt and Volt

Let’s get started by understanding the key definitions of Microvolt (µV) 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.

µV to V 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). So, to convert from microvolts to volts, divide the number of microvolts (V_(µV)) by 1,000,000.

V_(V) = V_(µV) ÷ 10⁶ = V_(µV) ÷ 1,000,000

\text{V}_\text{(V)} = \frac{\text{V}_\text{(µV)}}{1{,}000{,}000}

Or remember the µV-to-V conversion factor: 1 µV = 10^-6 = 0.000001 V

Examples

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

Example: Measuring Low-Level Signals in Radio Frequency Receivers

Radio frequency (RF) receivers are used in wireless communication, satellite systems, and radio astronomy to detect weak electromagnetic signals. These signals often have very low voltage levels, requiring precise measurement and conversion for proper tuning and signal processing.

An RF receiver detects a weak signal of 150,000 microvolts (µV), but engineers need the voltage expressed in volts (V) for system calibration and optimization.

Solution

Since 1 volt (V) = 1,000,000 microvolts (µV), we can convert 150,000 µV to volts by using the following formula:

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

$$\text{V}_\text{(V)} = \frac{150{,}000}{1{,}000{,}000} = \boxed{0.15 \text{ V}}$$

Therefore, the 150,000 µV output voltage of the signal is equivalent to 0.15 V.

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

Enter the value in microvolts – For this example, enter 150,000 into the From box.
View the result – The converter instantly calculates and displays the equivalent value in volts: 0.15 V.

FAQs

Is 1 volt or 1 microvolt larger?

A volt (V) is a million times bigger than a microvolt (µV). Here are the relationships between the units:

1 V = 10⁶ = 1,000,000 µV
1 µV = 10^-6 = 1 ÷ 1,000,000 = 0.000001 V

How to convert from microvolts to volts?

To convert voltage from microvolts (µV) to volts (V), follow these simple steps:

Write down the voltage value in microvolts (µV).
Multiply it by the value of a µV-to-V conversion factor: 10^-6 or 0.000001.
The result of the multiplication is the value of the voltage in volts (V).

Why do I need to convert from microvolts to volts?

Converting microvolts (µV) to volts (V) is necessary when working with larger voltage values in electrical, scientific, and engineering applications. Since 1 V = 1,000,000 µV, expressing voltage in volts simplifies calculations, ensures compatibility with standard electrical systems, and improves clarity in documentation.
