Common mistake Correct Remarks 25m 25 m ALWAYS with a space between the numerical value and the SI symbol 20°F, 20°C 20 °F, 20 °C ALWAYS with a space between the numerical value and the SI symbol 25m 25 m Unit symbols are NOT exponents 75 mts, 100lts 75 m, 100 l (or 100 L) Unit symbols are NOT abbreviations 25 ms, kgs, kWs 25 m, kg, kW Unit symbols are inaltered in the plural 50 m. 25 m NO end period, except as normal punctuation at the end of a sentence KW, kw kW See SI Prefixes kW/h kW.h i.e., power x time = energy amp A Use standard SI terminology 100 w, 500 pa 100 W, 500 Pa First letter of a SI symbol (named after a proper name) is always a capital 45 ° 45° Referring to angle measurements 125°K, 300 °K 125 K, 300 K The SI unit of thermodynamic temperature is kelvin (K) not °K 20 degree centigrade 20 degree Celsius "centigrade" (temperature scale) has been deprecated since 1948 kph km/h Use standard SI terminology 100 joules, 500 watts 100 joule, 500 watt When writting units in full derived from the proper name of individuals quilómetro/h km/h Do not mix unit names with unit symbols 5 kiloyears 5000 days SI prefixes are not used with angle and time units 30 sec 30 s Use standard SI terminology 750 cc, 750 cm3 750 cm³ Use standard SI terminology 75% 75 % By extension from the SI rules 1 mµm 1 nm Do not use compound prefixes 5 m (16.404 foot) 5 m (16 foot) Express the secondary value with an accuracy comparable to the original 25.000 (twenty-five thousand) 25 000 Except in tabular form, write 1234 (4 digits only), and 12 345 (5+ digits) duzentas gramas duzentos gramas Yeap! "grama" is a masculin noun in Portuguese... gravidade específica (*) massa volúmica For "specific gravity", when numerical value has units (e.g., 5 kg/m³) gravidade específica (*) densidade For "specific gravity", when numerical value has NO units (e.g., 1,0) densidade massa volúmica For "specific gravity", when numerical value has units (e.g., 10 kg/m³) (*) "gravidade específica" is a complete aberration in Portuguese!
