m
meter;mass;milli- m is the standard unit symbol for length in the International System of Units (SI). 1 meter is equivalent to 3.28 feet. m is also the standard symbol for mass; m is also the standard SI metric unit prefix milli- which represents one thousandth i.e. 10-3, of a given unit.
mAs
milliamperes-second - unit measure of electric charge acquired when multiplying the electric current in milliamperes (one thousandth or 10-3 of the standard unit for electric current the ampere) by the time in seconds. It is commonly used to describe the length of time that electrons are produced or passed through a given circuitry.
Mb
megabit — The megabit (also expressed as Mbit) is equivalent to one million (or 106) of the standard unit for digital information storage in telecommunications which is the bit.
MB
megabyte — The megabyte (also expressed as Mbyte) is equivalent to one million (106) of the standard unit for digital information storage in computing which is the byte.
MB/s
megabytes per second — The megabyte per second (not to be mixed up with the Mb/s -- megabits per second) is a unit of data transfer rate equivalent to one million (106) bytes per second over a given information network.
Mb/s
megabits per second — The megabit per second (not to be mixed up with the mbit/s – millibit per second, or Mbitps- megabit picosecond) is a unit of data transfer rate equivalent to one million (or 106) bits per second over a given information network.
Mc/s
megacycles per second — Megacyces per second is an oscillation rate equivalent to one million (or 106) of the standard unit of a single optical period over a second which is an optical cycle.
mcd
millicandela — The millicandela is equivalent to one thousandth (or 10-3) of the standard unit of luminous intensity that is the candela, which is the power emitted by a given light source in a particular direction.
MCT
mercury cadmium telluride — Mercury cadmium teluride (HgCdTe) is a specific alloy combination that allows one to obtain any optical absorption bandgap of the material between 0 and 1.5 electron volts (eV) making it completely transparent at photon energies and wavelengths below the energy gap in the infrared.
MeV
mega-electronvolt — A unit of energy that is equivalent to one million (106) of the unit of energy which is the electron volt (eV).
meV
milli-electronvolt — A unit of energy that is equivalent to one thousandth (10-3) of the unit of energy which is the electron volt (eV).
mF
millifarad — A unit of capacitance that is equivalent to one thousandth (10-3) of the standard unit for capacitance which is the farad.
MWIR
medium-wavelength infrared; mid-wave infrared
