2 cm – approximate width of an adult human finger; 2.54 cm – 1 inch; 3.08568 cm – 1 attoparsec; 3.4 cm – length of a quail egg [113] 3.5 cm – width of film commonly used in motion pictures and still photography; 3.78 cm – amount of distance the Moon moves away from Earth each year [114] 4.3 cm – minimum diameter of a golf ball [115]
The resulting radius was recorded as 0.842(1) fm, 5 standard deviations (5σ) smaller than the prior measurements. [2] The newly measured radius is 4% smaller than the prior measurements, which were believed to be accurate within 1%. (The new measurement's uncertainty limit of only 0.1% makes a negligible contribution to the discrepancy.) [12]
8.3 × 11.7: 1/2 4 = 0.0625 ... The untrimmed sizes are 3 to 4 cm larger and rounded to the nearest centimetre. ... The size is also smaller than its Swedish ...
Its size is 1.5 m × 2.1 m (5 ft × 7 ft). [13] According to the 2007 Guinness World Records, the largest published book in the world was The Little Prince printed in Brazil in 2007. Its size is 2.01 m × 3.08 m (6 ft 7 in × 10 ft 1 in). [14]
Even an entire beam of protons circulated in the Large Hadron Collider, a high energy physics experiment, contains ~ 3.23 × 10 14 protons, [5] each with 6.5 × 10 12 eV of energy, for a total beam energy of ~ 2.1 × 10 27 eV or ~ 336.4 MJ, which is still ~ 2.7 × 10 5 times lower than the mass–energy of a single gram of hydrogen. Yet, the ...
Their intercepts with the dashed lines show that when the volume increases 8 (2³) times, the surface area increases 4 (2²) times. The surface-area-to-volume ratio or surface-to-volume ratio (denoted as SA:V, SA/V, or sa/vol) is the ratio between surface area and volume of an object or collection of objects.

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]
