Frequently Asked Questions
How do I convert ampere to milliampere?
To convert ampere to milliampere, multiply the value in ampere by 1,000. For example, 1 ampere = 1,000 milliampere. Type any value above and the answer updates as you type.
How many milliamperes are in an ampere?
There are 1,000 milliamperes in 1 ampere. To convert amperes to milliamperes, multiply by 1,000 — for example, 10 amperes = 10,000 milliamperes. To go the other way, divide by 1,000.
How many amperes are in a milliampere?
There are 0.001 amperes in 1 milliampere. To convert milliamperes to amperes, multiply by 0.001 — for example, 10 milliamperes = 0.01 amperes. To go the other way, divide by 0.001.
How many milliamperes are in a microampere?
There are 0.001 milliamperes in 1 microampere. To convert microamperes to milliamperes, multiply by 0.001 — for example, 10 microamperes = 0.01 milliamperes. To go the other way, divide by 0.001.
How many amperes are in a kiloampere?
There are 1,000 amperes in 1 kiloampere. To convert kiloamperes to amperes, multiply by 1,000 — for example, 10 kiloamperes = 10,000 amperes. To go the other way, divide by 1,000.
How many microamperes are in an ampere?
There are 1,000,000 microamperes in 1 ampere. To convert amperes to microamperes, multiply by 1,000,000 — for example, 10 amperes = 10,000,000 microamperes. To go the other way, divide by 1,000,000.
How many amperes are in an abampere?
There are 10 amperes in 1 abampere. To convert abamperes to amperes, multiply by 10 — for example, 10 abamperes = 100 amperes. To go the other way, divide by 10.
How many amperes are in a statampere?
There are 3.335640952E-10 amperes in 1 statampere. To convert statamperes to amperes, multiply by 3.335640952E-10 — for example, 10 statamperes = 3.335640952E-9 amperes. To go the other way, divide by 3.335640952E-10.
What is the base unit for electric current conversions?
The ampere. Every one of the 13 units in this converter is defined relative to the ampere, so any two units convert directly in one step.
How many units does the Electric Current Converter support?
The Electric Current Converter handles 13 units. You can convert between any two of them, or see your value in every unit at once in the "All conversions" table.
How accurate is this electric current converter?
Conversions use exact definitions wherever one exists (for example the international inch is exactly 2.54 cm and the pound exactly 0.45359237 kg) and calculate in double precision. Choose how many significant digits to show — up to 15.
How do I use the Electric Current Converter?
