"a single-space should always be inserted between the numeric quantity and the symbol of the unit, e.g. 3 T magnet, and not 3T magnet. This becomes easier to remember and appreciate if one considers that the symbol is just a shortening of a word, i.e. using the same example, 3 tesla magnet, no-one would write 3tesla magnet!"
"a single-space should always be inserted between the numeric quantity and the symbol of the unit, e.g. 3 cm cyst, not 3cm cyst. The latter incorrect usage is seen all too commonly in radiology reports. This becomes easier to remember and appreciate if one considers that the symbol is just a shortening of a word, i.e. using the same example, "3 centimetre cyst", no-one would write "3centimetre cyst"!"
"solid lesions e.g. lung nodules, mm3 or cm3, are best"
"SI unit of temperature is the kelvin (K), although it is acceptable to use degree Celsius (°C) for everyday temperatures as a change of one degree Celsius is equal to a change of one kelvin (i.e. Δ(Τ) / °C ≡ Δ(Τ) / K)."
"For units of measurement the use of SI units (both base and derived units) in articles and cases on Radiopaedia.org is preferred. This is in line with best scientific practice and helps maintain consistency across the site."
"strictly-speaking the symbol should be 'l', i.e. the non-capital form of the letter 'L'. However, in view of the risk of mixing up 'l' with '1' in some fonts, it was decided in some countries, e.g. USA, Australia, to legally mandate the upper case for safety reasons"
"other countries, e.g. UK, have kept it as 'l'"
"SI unit of distance is the metre (m)"
"SI unit of mass is the kilogram (kg)"
"SI unit of time is the second (s)"
"SI unit of electrical current is the ampere (A), often shortened to amp"

"SI unit of amount of substance is the mole (mol)"
"For ionising radiation, SI units should be used even though older units (e.g. rad) remain in common use in a few countries (e.g. USA). It should be noted, that even though this is the case the USA's National Institute of Standards and Technology (NIST) "strongly discourages" the use of non-SI units 2."
