multiple of the unit they mean. They have used Greek words to show multiples, and Latin words to show submultiples. The French measure of length would be

Kilometre-1000 metres (Greek Chilioi 1000)
Hectometre-100

(Greek Hecaton 100)
DEKAmetre 10

(Greek Deka 10)
METRE 1 metre—the Unit of Length
Decimetre th (Latin Decem 10)
CENtimetre Toth (Latin Centum 100)
Millimetre Tooth

(Latin Mille

1000) And these prefixes always mean the same.

Kilo-" prefixed to a word always multiplies it by 1000, Hecto-" by 100, and Deka-" by 10. Deci-divides by 10, Centi-” by 100, and “Milli-” by 1000.

You may say that the words look hard to you. Most likely they do: you are not used to them. But in a very little time they would become familiar and easy. And so much time and trouble would be spared by the introduction of such a method into England, that we are tempted to wonder why it is not done. We must remember, however, that our merchants and tradesmen would be obliged to alter all their weights, and all, the figures in their books of account; besides which, it would take time to get the new system into work, and we should have the trouble of learning our present system, and the decimal system as well, so long as both were in use.
