The UBC was first published in 1927 by the International Conference of Building Officials, which was based in Whittier, California. It was intended to promote public safety and provided standardized requirements for safe construction which would not vary from city to city as had previously been the case.
[3] The current international standard for the metric system is the International System of Units (Système international d'unités or SI). It is a system in which all units can be expressed in terms of seven units. The units that serve as the SI base units are the metre, kilogram, second, ampere, kelvin, mole, and candela.
When the unit group has rank ≥ 1, a basis of it modulo its torsion is called a fundamental system of units. [1] Some authors use the term fundamental unit to mean any element of a fundamental system of units, not restricting to the case of rank 1 (e.g. Neukirch 1999 , p. 42).
As of 2019, UBC Library's collection comprises 8.3 million items, including 2.8 million e-books, 5.3 million microforms, 440,000 journal titles and more than 923,000 maps, videos and other multimedia materials. During the year 2018–2019, the UBC community downloaded 3.4 million ebooks and 7.4 million journal articles, the equivalent of 89 ...

The systems formalised the concept of a collection of related units called a coherent system of units. In a coherent system, base units combine to define derived units without extra factors. [4]: 2 For example, using metre per second is coherent in a system that uses metre for length and second for time, but kilometre per hour is not coherent.
A 99 B-Line bus at UBC Exchange. The internal campus street grid is mostly organized as a number of east–west roads intersecting a series of north–south malls. There are few through streets on campus as both Main Mall and University Boulevard are largely pedestrian streets, bisecting the campus in both the east–west and north–south directions.
