Frequently Asked Questions
What are the different voltage units?
Volts (V): The SI unit of electric potential difference. Millivolts (mV): One thousandth of a volt (10^-3 V). Kilovolts (kV): One thousand volts (10^3 V). Megavolts (MV): One million volts (10^6 V). Microvolts (µV): One millionth of a volt (10^-6 V). Nanovolts (nV): One billionth of a volt (10^-9 V). Picovolts (pV): One trillionth of a volt (10^-12 V). Abvolts (abV): CGS unit equal to 10^-8 volts. Statvolts (stV): CGS electrostatic unit equal to approximately 299.79 volts.
How precise are the conversions?
Our converter uses high-precision mathematical calculations and displays results with up to 10 decimal places. For most practical applications, 2-4 decimal places are sufficient. You can round the result as needed for your specific use case.
Can I convert negative voltage values?
Yes! Negative voltages are valid in electronics and represent a potential difference in the opposite direction. Simply enter a negative number in the input field, and the tool will convert it correctly.
What is the conversion formula between volts and millivolts?
To convert from volts to millivolts: millivolts = volts × 1000. To convert from millivolts to volts: volts = millivolts ÷ 1000. Our tool handles all these formulas automatically, so you don't need to memorize them!
What is the difference between AC and DC voltage?
AC (Alternating Current) voltage changes direction periodically, while DC (Direct Current) voltage flows in one direction. This converter handles the magnitude of voltage regardless of whether it's AC or DC. For AC, the value typically refers to RMS (Root Mean Square) voltage.
Why are there so many voltage units?
Different applications require different voltage scales. Electronics often work with millivolts or microvolts for signal processing, while power transmission uses kilovolts or megavolts. Having multiple units makes it easier to work with appropriate number ranges in different contexts.
What are abvolts and statvolts used for?
Abvolts and statvolts are units from the CGS (centimeter-gram-second) system. Abvolts are used in the electromagnetic CGS system (1 abV = 10^-8 V), while statvolts are used in the electrostatic CGS system (1 stV ≈ 299.79 V). They are mainly of historical interest but may appear in older scientific literature.
What is a typical household voltage?
Household voltages vary by region. In North America, standard household voltage is 120V. In Europe and many other parts of the world, it's 220-240V. Industrial applications often use 380V or 400V three-phase power. Use our converter to easily convert between these values and other units.
How do I convert between metric prefixes?
Metric prefixes follow powers of 10: milli (10^-3), micro (10^-6), nano (10^-9), pico (10^-12) for subunits, and kilo (10^3), mega (10^6), giga (10^9) for multiples. Moving from a smaller prefix to a larger one involves division by 1000 at each step, and vice versa for multiplication.
Is this tool free to use?
Absolutely! Our Voltage Converter is completely free to use, with no registration required. We believe in providing high-quality, accessible tools for students, engineers, and anyone who needs to perform voltage conversions quickly and accurately.
