In the standard system the conversion is that 1 gallon = 231 cubic inches and 1 inch = 2.54 cm, which makes a gallon = 3785.411784 millilitres exactly. For nutritional labeling on food packages in the US, the teaspoon is defined as exactly 5 ml, [ 22 ] giving 1 gallon = 3840 ml exactly.
Assuming an NH + 4 abundance of and an electron abundance of 10 −7 typical of molecular clouds, the formation will proceed at a rate of 1.6 × 10 −9 cm −3 s −1 in a molecular cloud of total density 10 5 cm −3. [180]
The size of CRTs increased over time, from 20 inches in 1938, [52] to 21 inches in 1955, [53] [54] 25 inches by 1974, 30 inches by 1980, 35 inches by 1985, [55] and 43 inches by 1989. [56] However, experimental 31 inch CRTs were made as far back as 1938. [57] In 1960, the Aiken tube was invented. It was a CRT in a flat-panel display format with ...
The greatest 24-hour rainfall was 4.93 in (125 mm) on August 1, 1926. The snowiest month on record was January 2014, with 30.3 in (77 cm) of snowfall. [92] The greatest calendar-day snowfall was 18.0 in (46 cm) on February 28, 1900. [93]
On March 19, 2013, an impact occurred on the Moon that was visible from Earth, when a boulder-sized 30 cm meteoroid slammed into the lunar surface at 90,000 km/h (25 km/s; 56,000 mph) creating a 20-meter crater. [139] [140] NASA has actively monitored lunar impacts since 2005, [141] tracking hundreds of candidate events. [142] [143]
