| 1385109 | 2014-10-02 06:57:00 | Why do they still quote volume in litres rather than cubic metres! What's wrong with "per cu-m" instead of per 1000 litres (or 1,000,000 cc or whatever)? Reminds me of the days of "3000 kB" instead of 3 MB Good question - But litres pertain generally to liquids (volume), that can be held, poured or flowed out. Whether if copious volumes of water supply or pouring from a 1.5 litre of coke. Most people can visualize (and readily know about litres) small to mid size volumes (in litres), compared to cubic meters, which not as common I suppose in everyday use. Litres for liquids, cubic meters for....hard to quickly relate readily to anything... Though cu-m pertain generally relates to dimensional (and seems to be more in industrial use) volume space - (e.g. engine size, warehouse storage, coolstore size, industrial bins, etc)- generally without any form of liquid involved. Historical terminology/nomenclature I think. |

| 1385112 | 2014-10-03 00:59:00 | River flows are measured in cubic metres per second ('cumecs') I used to live near the Waikanae river and have a feeling for 1 cumec because that was about the minimum allowed flow. It's not much. Most people would see it as just a stream A cubic metre of water weighs a tonne and a truck can carry 5 to 10 tons... easy to visualise Ocean currents are measured in cubic kilometres - it's a bit harder to visualise those! |
