The following table gives formula for the spring that is equivalent to a system of two springs, in series or in parallel, whose spring constants are and . [1] The compliance c {\displaystyle c} of a spring is the reciprocal 1 / k {\displaystyle 1/k} of its spring constant.)
One cubic inch (assuming an international inch) is equal to: 0.000578704 cubic feet (1 cu ft equals 1,728 cu in) Roughly 1 tablespoon (1.0 U.S. gallon = 256 U.S. tablespoons = 231 cubic inches) About 0.576744 imperial fluid ounces; About 0.554113 US fluid ounces; About 0.06926407 American/English cups; About 0.000450581 imperial bushels
If using the metric unit meters for distance and the imperial unit inches for target size, one has to multiply by a factor of 25.4, since one inch is defined as 25.4 millimeters. distance in meters = target in inches angle in mrad × 25.4 {\displaystyle {\text{distance in meters}}={\frac {\text{target in inches}}{\text{angle in mrad}}}\times 25.4}
Originally in 1945, the divisions were based on the ring inside diameter in steps of 1 ⁄ 64 inch (0.40 mm). [6] However, in 1987 BSI updated the standard to the metric system so that one alphabetical size division equals 1.25 mm of circumferential length. For a baseline, ring size C has a circumference of 40 mm. [7]
Sizes are often expressed as a fraction of an inch, with a one in the numerator, and a decimal number in the denominator. For example, 1/2.5 converts to 2/5 as a simple fraction, or 0.4 as a decimal number. This "inch" system gives a result approximately 1.5 times the length of the diagonal of the sensor.
The .450/400 2 3 ⁄ 8 inch Black Powder Express was loaded with a bullets from 210 to 270 grains (14 to 17 g) driven by 79 to 84 grains (5.1 to 5.4 g) of black powder. The .450/400 2 3 ⁄ 8 inch Nitro for Black was loaded with a jacketed 270 grain round nose bullet driven by 38 grains (2.5 g) of cordite.
Straw bales perform at about R-2.38 to 2.68 per inch, depending on orientation of the bales. [42] However, typical straw bale houses have very thick walls and thus are well insulated. Snow is roughly R-1 per inch. Brick has a very poor insulating ability at a mere R-0.2 per inch; however it does have a relatively good thermal mass.
