The order of magnitude of data may be specified in strictly standards-conformant units of information and multiples of the bit and byte with decimal scaling, or using historically common usages of a few multiplier prefixes in a binary interpretation which has been common in computing until new binary prefixes were defined in the 1990s..
An order of magnitude of time is usually a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years. In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year". In other cases, the quantity name implies the base unit, like "century". In most ...
So are 1 and 2, 1 and 9, or 1 and 0.2. However, 1 and 15 are not within an order of magnitude, since their ratio is 15/1 = 15 > 10. The reciprocal ratio, 1/15, is less than 0.1, so the same result is obtained. Differences in order of magnitude can be measured on a base-10 logarithmic scale in "decades" (i.e., factors of ten). [2]
Typical speed of car (freeway); cheetah—fastest of all terrestrial animals; sailfish—fastest fish; speed of go-fast boat. 40: 140: 90: 1.3 × 10 −7: Typical peak speed of a local service train (or intercity on lower standard tracks). 40.05: 144.17: 89.59: 1.335 × 10 −7: Land speed record for a human powered vehicle.

The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. [1] [2] The rise of easy popularization of ideas through the internet has greatly increased the relevant examples, but the asymmetry principle itself has long been recognized. [3]
13 things in the gigameter group Upper part: Gamma Orionis, Algol B, the Sun (centre), and other objects to scale. The gigametre (SI symbol: Gm) is a unit of length in the metric system equal to 1 000 000 000 meters (10 9 m). To help compare different distances this section lists lengths starting at 10 9 meters (1 gigameter (Gm) or 1 billion ...

Mathematics: √ 2 + 1 ≈ 2.414 213 562 373 095 049, the silver ratio; the ratio of the smaller of the two quantities to the larger quantity is the same as the ratio of the larger quantity to the sum of the smaller quantity and twice the larger quantity. Mathematics: e ≈ 2.718 281 828 459 045 087, the base of the natural logarithm.
