Additional Information The prefixes in the SI system are intended to create appropriately-sized units so the number is easily read and understood. For instance, consider the value No basic unit may have more than one prefix attached! | Take care to distinguish between capital and lower-case symbols. The general principle is that, if the prefix makes the unit bigger then the symbol for the prefix is a CAPITAL letter, with just three exceptions: kilo[k], hecto[h] and deca[da]. All the other prefixes (which make the unit smaller) are written in lower case. The table above makes this clear. The only 'awkward' one is that for 'micro' which is the Greek letter 'mu'. Similarly, if the unit is named after a person (like Watt, Newton, Joule etc.) the symbol for the basic unit is a CAPITAL letter (like W, N, J, etc.), but if the unit is written in full then a lower-case letter is used (like 18 watts, fifty-six newtons, 1045 joules, etc.). |
