Microvolts to Volts Converter

Enter the voltage in microvolts:

A Microvolts to Volts (μV to V) converter is an essential tool for converting extremely small electrical measurements into standard voltage units. This conversion is critical in sensitive electronics, biomedical instrumentation, and scientific research where minute voltages must be quantified.

Unit Definitions

• Microvolt (μV):

  • 1 μV = 0.000001 V (10⁻⁶ V)

  • Used for measuring:

    • Neural signals (EEG: 1-100 μV)

    • Cardiac signals (ECG: 100-5000 μV)

    • Sensor outputs (thermocouples, strain gauges)

    • Radio telescope signals

• Volt (V):

  • SI base unit of electrical potential

  • 1V = potential needed to move 1 coulomb with 1 joule

  • Common references:

    • AA battery: 1.5V

    • USB port: 5V

    • Household outlet: 120V/230V

Conversion Formula

The conversion uses direct metric scaling:

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

Scientific Notation:

$$V=\mu V\times {10}^{-6}$$

Step-by-Step Conversion Process

1. Obtain measurement in microvolts

2. Divide by 1,000,000 (or multiply by 10⁻⁶)

3. Express result in volts

Example Conversion:

$$250\text{ μV}÷1,000,000=0.00025\text{ V}$$
