Volt to Microvolt Converter

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

Definitions of Volt and Microvolt

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

V to µV 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 volts to microvolts, multiply the number of volts (V_(V)) by 1,000,000.

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

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

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

Examples

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

Example: Testing Electrical Noise in Sensitive Circuits

You are designing a high-precision amplifier for a scientific instrument. To ensure accuracy, you need to measure and minimize electrical noise in the circuit. Your oscilloscope displays the noise level as 0.000085 V, but for fine-tuned adjustments, you need the value in microvolts (µV).

Solution

Since 1 volt (V) = 1,000,000 microvolts (µV), we can convert 0.000085 V to microvolts by using the following formula:

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

$$\text{V}_\text{(µV)} = 0.000085 \times 1,000,000 = \boxed{85 \text{ µV}}$$

Therefore, the 0.000085 V output voltage of the scientific instrument is equivalent to 85 µV.

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

Enter the value in volts – For this example, enter 0.000085 into the From box.
View the result – The converter instantly calculates and displays the equivalent value in microvolts: 85 µV.

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 volts to microvolts?

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

Write down the voltage value in volts (V).
Multiply it by the value of a V-to-µV conversion factor: 10⁶ or 1,000,000.
The result from multiplication is the value of the voltage in microvolts (µV).

Why do I need to convert volts to microvolts?

Think of it like measuring raindrops with a bucket versus a teaspoon. Microvolts (µV) let you track tiny electrical signals that regular tools might miss. Here’s where it matters most:

Medical devices, like heart monitors or brainwave sensors, rely on microvolt precision to catch faint signals your body produces. Without it, a heartbeat or nerve impulse could go unnoticed.
Earthquake sensors use microvolts to detect ground vibrations too subtle for human senses. A fraction of a volt here could mean the difference between “normal” and “earthquake warning.”
Even your phone’s antenna uses microvolt-level signals to grab weak Wi-Fi or radio waves.

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