10.16 cm = 1.016 dm – 1 hand used in measuring height of horses (4 inches) 12 cm = 1.2 dm – diameter of a compact disc (CD) (= 120 mm) 15 cm = 1.5 dm – length of a Bic pen with cap on; 22 cm = 2.2 dm – diameter of a typical association football (soccer ball) 30 cm = 3 dm – typical school-use ruler length (= 300 mm)
Atmospheric pressure micrometer: small distances multimeter: electrical potential, resistance, and current nephoscope: to measure the speed and direction of clouds nephelometer: particle in a liquid odometer: distance travelled ohmmeter: electrical resistance opisometer: lengths of arbitrary curved lines orchidometer: testicle size in male ...
The equation for Rockwell hardness is =, where d is the depth in mm (from the zero load point), and N and h are scale factors that depend on the scale of the test being used (see following section). It is typically used in engineering and metallurgy. Its commercial popularity arises from its speed, reliability, robustness, resolution and small ...
For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
For example, aligning the rightmost 1 on the C scale with 2 on the LL2 scale, 3 on the C scale lines up with 8 on the LL3 scale. To extract a cube root using a slide rule with only C/D and A/B scales, align 1 on the B cursor with the base number on the A scale (taking care as always to distinguish between the lower and upper halves of the A scale).
Each of the formulas listed in the tables assumes that the roughness profile has been filtered from the raw profile data and the mean line has been calculated. The roughness profile contains n {\displaystyle n} ordered, equally spaced points along the trace, and y i {\displaystyle y_{i}} is the vertical distance from the mean line to the i th ...
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

Boltzmann constant: The Boltzmann constant, k, is one of seven fixed constants defining the International System of Units, the SI, with k = 1.380 649 x 10 −23 J K −1.The Boltzmann constant is a proportionality constant between the quantities temperature (with unit kelvin) and energy (with unit joule).
