"The length is about one meter ten."
Translation:La longueur est d'environ un mètre dix.
Is this similar to how some (many?) English speaking countries outside North America say "half eight" instead of "half-past eight" for 8:30?
That word, compulsory, drove me nuts in France. I found this explanation just now if anyone is interested: "Necessary suggests that you need something based on the internal logic of the situation. A dentist is necessary if you've broken a tooth. Is it necessary to make so much noise? Yes it's necessary! I've broken a tooth! Required suggests that a rule or procedure is operating. Compulsory elevates the statement out of the personal realm and into a higher, systemic level of requirement. Primary education is compulsory in Kenya. But we would not say I've broken a tooth! A dentist is compulsory!"
If you use a noun of measurement, use the verb être:
- la longueur / la largeur / la température / le poids / la profondeur / la surface / l'angle est de...
If you use the noun of the object measured, use the verb faire:
- l'île / le pont... fait X de long / de large
- la mer fait X de profondeur / de température
- le jardin fait X de surface
Justin is correct that a centimetre is not a standard SI unit. It is a one hundredth of a metre which is an SI unit (the metre, not the centimetre!) and the other measurements are supposed to be in powers of thousands (10^6, 10^3, 10^-3, 10^-6, etc.) However, in everyday life in countries like France and Australia centimetres are preferred over millimetres because they are easier to visualise. In the construction industry, millimetres are used because they need extra precision. If your wall is out by a millimetre it is easy to fix, if it's out by a centimetre it's a big gap (or overlap) to correct!
Centi- and milli- are official prefixes to the base units, which form other units. The centimeter isn't any less of a unit, it just isn't a base unit nor is a millimeter. There is no rule that the base units are supposed be demarcated by thousandths, they just are above one-hundred/below one-hundredth. The rule is that they are all powers of 10, and they will be used according to the ability to measure/precision necessary/habit. Five decaliters would work just as well as 500 milliliters or 0.5 liters as they are the same amount, but it just isn't the usual way of labeling.
In recipes, you can find "millilitres", "centilitres" and "décilitres" and in other professional fields some measures are more popular than others, depending on how precise you need to be or how often you use them : un décamètre in construction; un double-décimètre at school; un quintal (100 kg) de céréales in agriculture, etc.
