This article will show how to convert voltage measurement units from microvolts (µV) to kilovolts (kV). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Volt, Microvolt, and Kilovolt
Let’s get started by understanding the key definitions of Microvolt (µV), Kilovolt (kV), 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 Kilovolt (kV)?
A kilovolt (kV) is a unit of electrical potential equal to one thousand volts (1,000 V). Think of it like measuring water pressure in a garden hose versus a fire hydrant. Kilovolts help quantify high-voltage systems where standard voltage measurements are too small to be practical.
µV to kV 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 kilo- represents a multiplier of 103 (1,000).
So, to convert from microvolts to kilovolts, divide the number of microvolts (V(µV)) by 10-9 (0.000000001)
V(kV) = V(µV) ÷ 109 = V(µV) ÷ 1,000,000,000
Or remember the µV-to-kV conversion factor: 1 µV = 10-9 = 0.000000001 kV

Examples
Now, let's look at an example that illustrates the calculations required to convert from microvolts to kilovolts (µV to kV).
Example: Measuring Soil Moisture Sensor Voltage in Precision Agriculture
Atmospheric electricity research studies natural electrical events in the Earth's atmosphere, particularly lightning. Special sensors can detect and record high voltage readings in microvolts (µV).
From the latest reading, a sensor detects a lightning event that produces 2,100,000,000 µV. To facilitate analysis and comparison, you need to convert the voltage to kilovolts (kV).
Solution
Since 1 kilovolt (kV) = 1,000,000,000 microvolts (µV), we can convert 2,100,000,000 µV to kilovolts by using the following formula:
Therefore, the 2,100,000,000 µV output voltage of the sensor is equivalent to 2.1 kV.
To solve the problem with our calculator, follow the steps below:
- Enter the value in nanovolts – For this example, enter
2,100,000,000into theFrombox. - View the result – The converter instantly calculates and displays the equivalent value in kilovolts:

FAQs
Is 1 kilovolt or 1 microvolt larger?
A kilovolt (kV) is a billion times bigger than a microvolt (µV). Here are the relationships between the units:
1 kV = 109 = 1,000,000,000 µV1 µV = 10-9 = 1 ÷ 1,000,000,000 = 0.000000001 kV
How to convert from microvolts to kilovolts?
To convert voltage from microvolts (µV) to kilovolts (kV), follow these simple steps:
- Write down the voltage value in
microvolts (µV). - Multiply it by the value of the
µV-to-kVconversion factor:10-9or0.000000001. - The result of the multiplication is the value of the voltage in
kilovolts (kV).
Why do I need to convert from microvolts to kilovolts?
High-voltage systems, such as those found in particle accelerators, aerospace instrumentation, or atmospheric research, often specify voltage in kilovolts. Converting from microvolts to kilovolts provides a more intuitive and standardized value.
Instead of managing huge numeric figures in microvolts (where 1 kV = 1,000,000,000 µV), the conversion streamlines the data, making it easier to interpret and compare across different systems.
You now know how to convert voltage from microvolts (µV) to kilovolts (kV). You can quickly use our calculator to convert between the voltage measurement units to save time for future calculations.
