How many millihenries equal 10 000 microhenries?

In the metric system, the prefix "micro" means one-millionth (1/1,000,000) and "milli" means one-thousandth (1/1,000). This means that there are 1,000 microhenries in a single millihenry. To convert from microhenries to millihenries, you must divide the value by 1,000. By moving the decimal point three places to the left, 10,000 microhenries becomes 10 millihenries. The other options are incorrect because they result from moving the decimal point the wrong number of places. Always remember that the step between micro and milli is exactly a factor of 1,000.
