A decametre (International spelling as used by the International Bureau of Weights and Measures and by most English speaking countries, [1] [2] United States spelling dekameter or decameter [3] [4]), symbol dam ("da" for the SI prefix deca-, [1] "m" for the SI unit metre), is a unit of length in the International System of Units (SI) equal to ten metres.
The millimetre (SI symbol: mm) is a unit of length in the metric system equal to 10 −3 metres ( 1 / 1 000 m = 0.001 m). To help compare different orders of magnitude , this section lists lengths between 10 −3 m and 10 −2 m (1 mm and 1 cm).
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
The CGS-to-SI correspondence of electromagnetic units as given was exact prior to the 2019 revision of the SI, until which the magnetic constant μ 0 was defined as 4π × 10 −7 N⋅A −2. As from the redefinition, μ 0 has an inexactly known value when expressed in SI units, with the exactness of the electromagnetic unit correspondence ...
The tapes are checked over master gauges at 0.001 in (0.025 mm) accuracy for standard tapes up to 144 inches (3,658 mm). [ 3 ] Precision diameter tapes are used in precision or advanced manufacturing industries, such as aero-space field and the plastic pipe industry.

61 000 Mm 2 Surface area of Jupiter , [ 93 ] the "surface" area of the spheroid (calculated from the mean radius as reported by NASA). The cross-sectional area of Jupiter, which is the same as the "circle" of Jupiter seen by an approaching spacecraft, is almost exactly one quarter the surface-area of the overall sphere, which in the case of ...
