Volts and microvolts are units of measurement for electrical voltage, which is a measure of the potential difference between two points in an electric circuit. Voltage is often described as the “push” that drives electric current through a circuit.
The volt is the standard unit of measurement for electric potential difference or voltage. It is named after the Italian physicist Alessandro Volta. One volt is defined as the electric potential difference across a conductor when a current of one ampere (A) flows through it, resulting in a power dissipation of one watt (W). In other words, 1 volt is the potential difference that will cause 1 ampere of current to flow through a resistance of 1 ohm.
The microvolt is a much smaller unit of measurement for electric potential difference. The prefix “micro-” signifies one millionth (1/1,000,000), so 1 microvolt is equal to 0.000001 volts. Microvolts are used to measure very small voltage differences, often in sensitive scientific and engineering applications.
To convert volts to microvolts, you can use the following conversion factor:
1 volt = 1,000,000 microvolts
This conversion factor indicates that there are 1 million microvolts in one volt. So, to convert a value in volts to microvolts, you simply need to multiply the value in volts by 1,000,000.
Mathematically, the conversion formula is:
Microvolts = Volts × 1,000,000
Example – Convert 3 volts to microvolts
Ans. V(µV) = 3V × 106 = 3000000 µV
| Volts (V) | Microvolts (µV) |
| 0 V | 0 µV |
| 0.000001 V | 1 µV |
| 0.00001 V | 10 µV |
| 0.0001 V | 100 µV |
| 0.001 V | 1000 µV |
| 0.01 V | 10000 µV |
| 0.1 V | 100000 µV |
| 1 V | 1000000 µV |
There are 1,000,000 (1 million) microvolts in one volt.
To convert volts (V) to millivolts (mV), multiply the voltage value in volts by 1000. Formula: Millivolts = Volts × 1000.
1 volt is equal to 1000 millivolts (mV).
To convert microvolts (µV) to volts (V), divide the microvolt value by 1,000,000. Formula: Volts = Microvolts ÷ 1,000,000.
250 millivolts (mV) is equal to 0.25 volts.
The electronvolt (eV) is a unit of energy, not voltage. However, you can convert voltage to energy if you're dealing with the charge of an electron. 1 electronvolt is equal to the charge of an electron (approximately 1.602 x 10^-19 coulombs) multiplied by 1 volt. Formula: Energy (eV) = Charge (Coulombs) × Voltage (V).
