We have tried to be accurate with the above table but cannot be held responsible for inaccuracies.
Go back to first principals and double check your calculations if the result is 'mission critical'.

Remember that you cannot create energy only convert it. Likewise, you will not find a conversion from pounds to metres - the basic units must remain the same - mass converted to mass, length converted to length, et al.

You won't usually find a conversion from kilograms to grams - the prefix 'kilo' means '1,000' so a kilogram is in fact 1,000 grams in the same way as a kilometer is 1,000 metres [or about 1,000 yards in 'old money']. I have put a few in the table because visitors have asked for them. More prefixes can be found on another table.

One handy metric link between units to remember is that 1 Litre [1000cc] of pure water weighs 1 kilogram.

More information on the SI System (Le Système International d'Unités) base units and definitions.
