U

 

UK
See 'Great Britain' under 'G' above

Under-
Words using under as a prefix are normally one word, eg underachieve, underact, underdeveloped, undermanned, underprivileged, undersigned, undervalue.

Under way
Two words, not hyphenated.

Units of measurement
The College uses the International System of Units (SI), which is a standard version of the metric system:

Type Unit
(use lower case)
Abbreviation
Length  metre m
Mass   kilogram  kg
Time 

second

hour

sec

hr

Volume millilitre ml
Electric current  amp A
Thermodynamic temperature  kelvin 
Luminous intensity  candela  cd
Amount of substance  mole  mol 

Exceptions:

  • celsius, centigrade use either term. Do not use the degree sign.
  • fahrenheit is not an SI unit but if it is necessary to use it, it is capitalised.
  • blood pressure in mmHg and haemoglobin in g/dl.

Unnecessary words
Some words add nothing but length to your prose. Use adjectives to make your meaning more precise and try to write short, concise sentences. If you think a word in your sentence may be unnecessary, omit the word and read the sentence aloud. If the sentence retains its meaning, the word may be best omitted. 

Some examples of common words which can be omitted are just and that, eg ‘We were hoping that he would come back just a bit later’ can be shortened to ‘we were hoping he would come back a bit later’.

US
When referring to the United States use US, not 'USA' - there is no need to spell out even at first mention. 'America' is technically the continent but is a commonly used reference for the US.

Underline
Use italics to emphasise a point, not underline.
