The lumen (symbol: lm) is the unit of luminous flux, a measure of the perceived power of visible light emitted by a source, in the International System of Units (SI). Luminous flux differs from power ( radiant flux ), which encompasses all electromagnetic waves emitted, including non-visible ones such as thermal radiation ( infrared ).
Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is between 1 meter to 1 millimeter.. The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length.
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, [3] [4] see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range ...
A ruler, depicting two customary units of length, the centimeter and the inch. A unit of length refers to any arbitrarily chosen and accepted reference standard for measurement of length. The most common units in modern use are the metric units, used in every country globally. In the United States the U.S. customary units are also in use.
The basic module (M) is a unit of distance equal to one hundred millimetres (100 mm). The myriametre (mym) is a unit of distance equal to ten kilometres (10 km). The hebdometre is a unit of distance equal to ten megametres (10 Mm). The spat (S) is a unit of distance equal to one terametre (1 Tm).
The 40CTC (40 mm Cased Telescoped Cannon) is a 40 mm autocannon and the central component of the Franco-British 40CTAS (40 mm Cased Telescoped Armament System) developed by CTA International. It is designed to fire 40mm telescoped ammunition . [ 2 ]
The only current 40×53 mm type is the M1001, a canister round filled with one-hundred and fifteen 17-grain 2.0-inch long flechettes. During the late 1960s, Nortronics was developing the XM678 . References have listed different projectile loads ranging from thirty-two 0.24 inch carbide pellets up to fifty-four 30 grain (1.94 gram) tungsten pellets.
A foot-candle (sometimes foot candle; abbreviated fc, lm/ft 2, or sometimes ft-c) is a non-SI unit of illuminance or light intensity. The foot-candle is defined as one lumen per square foot. This unit is commonly used in lighting layouts in parts of the world where United States customary units are used, mainly the United States. [ 1 ]
