One milliampere is one-thousandth of an ampere.

Explanation:
In SI units, milli- means 10^-3. That means one milliampere equals 0.001 ampere. So the statement is true: 1 mA = 0.001 A, and equivalently 1 A = 1000 mA. To convert, multiply by 1000 when going from amperes to milliamperes, or multiply by 0.001 (divide by 1000) when going from milliamperes to amperes. For example, 5 mA is 0.005 A. The other options don’t reflect a definite, exact relationship between milliampere and ampere.
