Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...
l/km (L/km) Use L/km to get "L/km" l/km impgal/mi; l/km usgal/mi; miles per imperial gallon mpgimp mpgimp mpgus; miles per US gallon mpgus (mpgUS, mpgU.S.) Use mpgUS to get "US" Use mpgU.S. to get "U.S." mpgus will give "U.S." if spelling is set to US & "US" otherwise mpgus mpgimp; imperial gallons per mile impgal/mi impgal/mi; US gallons per mile
e3 (thousand) e6 (million) e9 ; e12 ; e15 (quadrillion) Engineering notation can only be applied to simple units—temperatures, combinations, and some other special units will not work. Some examples using engineering notation follow. {{convert|123.4|e3m2}} → 123.4 thousand square metres (1.328 × 10 ^ 6 sq ft)

vehicle-kilometre (vkm [1]) as a measure of traffic flow, determined by multiplying the number of vehicles on a given road or traffic network by the average length of their trips measured in kilometres. [2] vehicle-mile (vehicle miles traveled, or VMT [1]) same as before but measures the trip expressed in miles.
The formulas involved can be complex and in some cases, such as in the ECEF to geodetic conversion above, the conversion has no closed-form solution and approximate methods must be used. References such as the DMA Technical Manual 8358.1 [ 15 ] and the USGS paper Map Projections: A Working Manual [ 16 ] contain formulas for conversion of map ...
Because of the identity property of multiplication, multiplying any quantity (physical or not) by the dimensionless 1 does not change that quantity. [5] Once this and the conversion factor for seconds per hour have been multiplied by the original fraction to cancel out the units mile and hour, 10 miles per hour converts to 4.4704 metres per second.
The unit prefixes are always considered to be part of the unit, so that, e.g., in exponentiation, 1 km 2 means one square kilometre, not one thousand square metres, and 1 cm 3 means one cubic centimetre, not one hundredth of a cubic metre. In general, prefixes are used with any metric unit, but may also be used with non-metric units.
