Title: Different units for measuring the amounts of floodwater Post by: Worcester_Passenger on February 20, 2014, 02:37:11 I get very confused when the news reports talk of removing "tonnes" of water. To me water comes (or goes) in gallons or litres.... That's retail water. Wholesale water comes in cubic metres, each of which weighs one tonne. The Americans use the acre-foot, an area of one acre (220 yards x 22 yards) that is one foot deep. This equates to 1233 cubic metres.

One tonne of water is 1 cubic metre or 1000 litres Title: Different units for measuring the amounts of floodwater Post by: stuving on February 20, 2014, 09:48:15 Most of us find it easier to make sense of rainfall in millimetres, since both large areas (in square metres or square anythings) and volumes of water are hard to visualise and their ratio ever more so. So why, you may wonder, do the French use litres per square metre instead? Of course it's exactly the same quantity. Another example of the way us and the French will find different ways of doing the same thing wherever we can?

Which nicely shows that an acre isn't that random, and can be visualised easily by fans of both racing and cricket as furlong x wicket... ;D Paul Title: Different units for measuring the amounts of floodwater Post by: SDS on February 20, 2014, 15:10:58 So how many chains cubed of water is a tonne then? :-p :-p
