Physics Symbols and the SI International System System of Units physical common name of symbol unit expressed unit expressed quantity symbols unit for unit in base units in other SI units Length Distance ldrxyzs meter m Base Unit Area A m2 Volume V.

Ma in physics means. Voltage current and resistance. A often informally abbreviated to amp is the SI base unit used to measure electrical currents. In physics the ampere symbol.

A milliampere second mAs is a unit of measure used in X-ray imaging diagnostic imaging and radiation therapy. But technically the m in this relationship refers to inertial mass as opposed to gravitational mass--even though both masses still appear to be the same thing. In classical physics F and m are phenomenological quantities which are specified by other relations.

You can postulate some force law and then make predictions for the motion. Mass in physics quantitative measure of inertia a fundamental property of all matter. The SI prefix milli represents a factor of 10-3 or in exponential notation 1E-3.

The unit is named for the 18th and 19th century French physicist Andre-Marie Ampere who studied electromagnetism. So you can take some amount of matter and on the basis of that assign to m some value. 0 5 10 15 20 30 40 50 60 70 80 90 100.

The abbreviation mA denotes the International System unit for electrical current known as the milliampere. The Mighty F ma. Academic Science Mathematics.

So 1 milliampere 10-3 ampere. Use this page to learn how to convert between amperes and milliamperes. 1 ampere is equal to 1 A or 1000 mA.
