Grade (slope) The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper ...
The 37.5 mm length is not derived by a certain scale ratio. While HO scale is a 1:87 scale (3.5 mm to 1 foot), resulting in a 16.5 mm ( 0.65 in) gauge from real life prototype 1,435 mm ( 4 ft 81⁄2 in) standard gauge standard gauge. Conversely, modeling standard gauge in Lego trains would yield a scaling of (37.5:1435 =) 1:38.3.

The Van 't Hoff equation relates the change in the equilibrium constant, Keq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, ΔrH⊖, for the process. The subscript means "reaction" and the superscript means "standard". It was proposed by Dutch chemist Jacobus Henricus van 't Hoff in 1884 in his book ...
A taper pin is a fastener used in mechanical engineering. They are steel rods with one end having a slightly larger diameter than the other. Metric taper pins have a taper of 1:50. [ 1] A 1:50 taper means that one end of a 50 mm long bar will be 1 mm smaller in diameter than the other end. Inch-sized taper pins have a slightly smaller taper ...
1:48 scale is a scale commonly used in diecast models, plastic models made from kits, and construction toys.It is especially popular with manufacturers of model aircraft and model trains, where it is known as "O scale". 1:48 is also a popular scale among Lego enthusiasts, since it is approximately the scale of the Lego minifigure relative to a six-foot tall human.
25.4 μm. A thousandth of an inch is a derived unit of length in a system of units using inches. Equal to 1000 of an inch, a thousandth is commonly called a thou / ˈθaʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils ). The words are shortened forms of the English and Latin words for "thousand ...
Various scales may be used for different drawings in a set. For example, a floor plan may be drawn at 1:50 (1:48 or 1 ⁄ 4 ″ = 1′ 0″) whereas a detailed view may be drawn at 1:25 (1:24 or 1 ⁄ 2 ″ = 1′ 0″). Site plans are often drawn at 1:200 or 1:100. Scale is a nuanced subject in the use of engineering drawings.
