experts call 1000 kg metric ton just because meter is a unit that measures lenght. "Monty" escreveu na mensagem ...

Why do you call the International System of Units a decimal system of
measurement? Isn't the Imperial system of units a decimal system? What have to do road signs with a system of units? I've heard in United Kingdom, people have the same unit for money and weight.

wrote: Why do you call the International System of Units a decimal system of measurement? the main features of the metric system were the standard set of inter-related base units and a standard set of prefixes in powers of ten. These base units are used to derive larger and smaller units that could replace a huge number of other units of measure in existence. Although the system was first developed for commercial use, the development of coherent units of measure made it particularly suitable for science and engineering. Isn't the Imperial system of units a decimal system? No. What have to do road signs with a system of units? I don't know! I've heard in United Kingdom, people have the same unit for money and weight.

No. You *could* specify a distance as 3.5 feet or a weight as 5.25 pounds, but it is more usual either to express things as fractions (5/8 inch *) or else in a mixture of units (3 feet 6 inches or 5 pounds 4 ounces). So, in normal usage, the imperial system tends not to be a decimal system. The other connotation of "decimal" is that units in the same system are related by powers of ten. They certainly are in the SI/metric system. They are not in the imperial: various multiples are used (16 ounces/pound, 12 inches/foot, 8 pints/gallon) but I cannot think of any example of two units which are related by the only sensible ratio - 10 (given that we have 10 digits and so count in base 10). (*) Analogue scales, such as rulers, tape measures and weighing scales, tend to be divided into power-of-two divisions of the relevant unit: half, quarter, eighth, sixteenth and so on as far as the accuracy that you want to claim in your measurement. |

The metric system of measurement is far superior. Since a gram is the weight of on cubic centimeter of water, this make conversion for length/volume to weigh quite simple, as a 1000 cubic centimeters/ or one liter will weigh 1000 grams or a kilogram. How many pounds are in a quart of water? How many cubic inches are in a quart? I would have to answer the above after a trip to Google. |

But that's because it's a _decimal_ system, _not_ because the quantities themselves are useful. In fact, in real life they're damn inconvenient, because they don't relate well to sizes and quantities we humans actually use. Probably that's why the system is based on metres, kg and seconds, which we can all relate to on a human scale. |

Once more, with feeling: In all English speaking countries, "tonne" means 1,000kg. "Ton" usually means 2,000lb in the UK, and 2,000lb in the US. But it means something different when referring to a ship. Then there's the "tun".... You are still getting it wrong Mr K :-) A ton is 20 cwt. A cwt is 112lb in the UK but only 100lb in the US therefore a UK ton is 2,240lb while a US ton is 2,000. I don't know of a difference when referring to a ship but maybe it's the UK ton of 2,240lb which I've always taken it to be. -- Faster, cheaper, quieter than HS2 and built in 5 years; UKUltraspeed http://www.500kmh.com/ |

However, I do recall a 2,000lb ton termed a "short ton" when I was a schoolboy. Yes, that's the US ton, the UK ton is the long ton. I don't know of a difference when referring to a ship but maybe it's the UK ton of 2,240lb which I've always taken it to be. Here's the skinny on that: https://en.wikipedia.org/wiki/Tonnage That's a whole new bag of worms I've decided to not go too near :-)) -- Faster, cheaper, quieter than HS2 and built in 5 years; UKUltraspeed http://www.500kmh.com/ |
