Sean Waters Posted November 15, 2004 Report Share Posted November 15, 2004 Re: Vehicle Construction - Size vs Mass Hey Aroooo, The term tons(I've also seen it spelled tonnes) when used with ship size is not a unit of weight but a unit of volume (the amount of water displaced by the hull) so a 1000 tons wooden ship is the same size as a 1000 tons metal ship though the dead weight of each is different. It's one of those confusing old English measuring systems. I'm suddenly blank on the exact size in cubic meters but only number in my head this early in the morning is 4 cubic meters but that seems too small 1 cubic metre of water weighs one metric tonne in earth normal gravity, if I remember right, so you were over not under. It doesn't seem right until you think about packing bags of sugar into a big cube. 10x10x10 bags of sugar is 1000 bags: I metric tonne is 1000kg. An imperial ton (this is British weights, you may be a little different over there!) weighs 2240 lbs (or 20 hundredweight), so a tonne and a ton are pretty similar weight wise. If the stats talk about displacement, go by length, if they talk about actual 'on the scales' weight, go by weight. Quote Link to comment Share on other sites More sharing options...
