Unit of the day...

Today there isn't a Unit of the day, instead 'the space' is considered. When values are written with symbols a space should be left between the numerical value and the unit symbol.
Examples: one newton = 1 N (not '1N')
ten newtons = 10 N (not '10N')
thirty four point eight one millimetres = 34.81 mm (not '34.81mm')
In this last example a dot is used to show the decimal sign/marker.
In some countries a comma is used as the decimal sign/marker. More information about this will be found in the book ĎA Dictionary Of International Unitsí by Philip Bladon.

Compared to the large, expensive, and technical ISO documents from Geneva this dictionary provides information on SI (metric) units in a clear, interesting and non-technical way, it is good value.

International Units and their symbols - an international language.
