# Ampere per meter squared (A/m 2)

Ampere per meter squared (A/m2) is a measure of the strength of the magnetic field produced by an electric current. It is commonly used to express the strength of the magnetic field produced by electrical cables and other conductors. What is the value of 1 ampere? The value of 1 ampere is the current that will flow through a conductor when a voltage of 1 volt is applied across it.

### How is 1m defined?

The definition of a meter has changed over time. The first definition, in 1793, was one ten-millionth of the distance from the equator to the North Pole. In 1960, the meter was redefined as the distance light travels in a vacuum in 1/299,792,458 of a second. In 2019, the meter was once again redefined, this time in terms of the Planck constant. The new definition is: the meter is the distance light travels in a vacuum in 1/299,792,458 of a second times the Planck constant.

What is the SI unit of Metre per second square? The SI unit of Metre per second square is the metre. This is because the metre is the SI unit of length, and the second is the SI unit of time. The square of the metre is the metre squared, and the square of the second is the second squared. Thus, the SI unit of Metre per second square is the metre squared per second squared. What is the value of mA? The value of mA varies depending on the particular application. For example, in the case of a smart grid, mA might refer to the value of current required to operate a certain type of equipment. How many volts are in 1 amp? There are 1,000 volts in 1 amp.
