The Fuller calculator, sometimes called Fuller's cylindrical slide rule, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. This creates an instrument of considerable precision – it is equivalent to a traditional slide rule 25.40 metres (1,000 inches) long. It was invented in 1878 by George Fuller ...
Dollhouse for a dollhouse scale for 1:12 dollhouses. Commonly used for mini armor. Used for 12 mm, and 12.5 mm figure scale miniature wargaming. 1:128: 3 ⁄ 32 in: 2.381 mm A few rockets and some fit-in-the-box aircraft are made to this size. 1:120: 0.1 in: 2.54 mm: Model railways (TT) Derived from the scale of 1 inch equals 10 feet.TT model ...
Model railway scales and gauges are standardized in NEM 010, [1] which covers several gauges for each scale. Narrow gauges are indicated by an additional letter added after the base scale as follows: no letter = standard gauge (1,250–1,700 mm or 49.2–66.9 in) m = metre gauge (850–1,250 mm or 33.5–49.2 in) e = narrow gauge (650–850 mm ...

1,435 mm (4 ft 8 + 1⁄2 in) standard gauge. S scale (or S gauge) is a model railroad scale modeled at 1:64 scale, S scale track gauge (space between the rails) is 22.48 mm (0.885 in). [1][2][3] S gauge trains are manufactured in both DC and AC powered varieties. S gauge is not to be confused with toy train standard gauge, a large-scale ...
The SR-50 measured 5-3/4 inches long by 3-1/8 inches wide by 1-3/16 inches high (147 mm by 78 mm by 31 mm) and was powered by a rechargeable NiCad battery pack, built from three welded AA cells. It had 40 keys, and flat sliding switches for degrees / radians and on/off. "SR" stood for " slide rule." The SR-50 had a red LED display with a signed ...
