Frequently Asked Questions
How accurate is the electric current unit converter?
Our converter uses precise conversion factors based on international standards. Results are accurate to multiple decimal places, suitable for professional use in electrical engineering and electronics.
What is an ampere?
An ampere (A) is the SI base unit of electric current. It represents the flow of one coulomb of electrical charge per second through a conductor.
How many milliamperes are in an ampere?
1 ampere equals exactly 1,000 milliamperes (mA). This is a standard metric conversion.
What current do household circuits typically use?
Standard household circuits in the US are typically rated at 15 or 20 amperes. Individual appliances may draw anywhere from a few milliamperes to several amperes.
What is the difference between amperes and volts?
Amperes measure electric current (the flow of charge), while volts measure electric potential or voltage (the force pushing the charge). Think of current as the amount of water flowing and voltage as the water pressure.
How do I convert microamperes to milliamperes?
To convert microamperes to milliamperes, divide by 1,000. For example, 5,000 μA equals 5 mA.
What are nanoamperes used for?
Nanoamperes (10^-9 amperes) are used to measure very small currents in sensitive electronic devices, sensors, and low-power circuits.
Is it dangerous to work with high amperage?
Yes, electric current as low as 0.1 amperes (100 mA) can be fatal if it passes through the human heart. Always follow proper safety procedures when working with electrical systems.
