Measurement Units. It contains approximately 300 million characters,[92] so two copies would fit onto a CD-ROM and still have 50 megabytes (or about 11 bibles) left over. Units of measurement provide standards so that the numbers from our measurements refer to the same thing. More specifically, it’s equal to one-third of 1 horsepower, i.e. Multiples and Submultiples. There have been numerous proposals and usage of decimal time, most of which were based on the day as the base unit, such that the number of units between any two events that happen at the same time of day would be equal to the number of days between them multiplied by some integer power of ten. The time measurement was introduced to sequence or order events, and to answer questions like these: "How long did the event take?" Solar mass (M☉ = 2.0×1030 kg) is also often used in astronomy when talking about masses of stars or galaxies; for example, Alpha Centauri A has the mass of 1.1 suns, and the Milky Way has a mass of approximately 6×1011 M☉. Larger intermodal containers are commonly described in multiples of TEU, as are container ship capacities. It is stacked 16 inches (40.6 cm) deep with the other measurements kept the same as a cord, making it ​1⁄3 of a cord; however, regional variations mean that its precise definition is nonstandardized.[42].
