TONNE AND TON

I would like to remind all users that, with respect to the unit of measurement corresponding to 1000.0kg, there are differences, depending on the country where you are, and that Mathcad takes this into account. so you have to be careful:

Hello F.M.

Thanks for the information.

Kind regards.

Denis.

Re: TONNE AND TON

Thank you for completing

Re: TONNE AND TON

Strictly speaking,

1 Tonne =1 metric tonne =1000kg

1 Ton = 1 imperial Ton (US) =2000 lb

what is missing is

1 Ton = 1 imperial ton (UK) =2240 lb

14 pounds = 1 stone; 8 stones = 1 hundredweight; 20 hundredweight = 1 ton)

Re: TONNE AND TON

1 metric tonne = 1,000 kg

1  long ton  = English ton = 1,016 kg (UK Ton= 2240lb)

1  short ton = about 907 kg (US Ton= 2000lb)

Re: TONNE AND TON

Regarding the force, I would like to add, and to remember that:

Re: TONNE AND TON

Way back, when I was in school and introduced to the "metric system," the one major advantage that I saw over the "English" system was the complete separation of terminology between mass and force.  Mass was grams, or kilograms; force was Dynes or Newtons.  Things were clear, not like the English system where pounds could be force or mass.  Equations were much simpler--devoid of the hated "g".

I was (and still am) very disheartened when I encounter a "kilogram force".  I have been forced (by location) to learn and use the English unit system, and have gotten used to it.  But please, please, please:  Hold firmly to kilograms and Newtons, grams and Dynes.  Practice the true religion; put "kgf" behind you!

Re: TONNE AND TON

You're absolutely right, but those units are used, especially in engineering, as you well know,  when it comes to large masses or forces so write numbers relatively small, otherwise, for exmple, to write 10 tons (tonnef), you should write 98066,500N.

Re: TONNE AND TON

Or, using the popular argument for metrics and prefixes, you could write 98 kN.
