i think 2240 lbs in a ton which is almost exaccerly the same as a tonne. two tons almost exactly.

yup, agree with tcm. Or a lb is .454 kg (read a bag of flour) and 1000 kg is a tonne. A tonne is within 98% of a ton

5600/2240=2.5 Tons DOWN LOAD THIS TO THAT FOR FUTURE REFERENCE

There is exactly 2.2046lbs in a Kilo so therefor if you multiply a kilo by 1000 you get a metric tonne. Or if you are working in Imperial weights 2240lbs in a ton and 112lbs in a cwt. and 14lbs in a stone.

5600 pound = 2.54tonne
5600 pound = 2.8 ton
there is a great conversion site here which will calculate just about anything

ah yes, assumed being a European site they'd be using sensible units!

i was right about the number of pounds, wrong about the division so its 2.5 tons

Factors ...
1 metre = 1.0936 yards
1 inch = 2.54 cms
1 ton = 1.01605 metric ton ( or tonne as single word)
1 tonne = 0.984206 ton
1 lb = 0.453592 kg
1 kg = 2.20462 lbs
1 imp gallon = 4.54596 litres
1 litre = 0.219969 imp gallon
The above are exact by definition and as per ASTM - IP Table 1.
Just thought some may like to have them jotted down !!
If you use a Palm PDA - then you can get an excellent conversion program from : www.mattmarsh.net
For PC .... Conversion Plus at www.mrhvac.com which just about covers everything !!

Re: Factors ...
It must be an age thing, i cant believe so much lather and error over a very simple question.Didn't you lot have all these weights and measures beaten into you as children?
And for ten bonus points how many square metres in an acre?

If you're trying figure out your vessel's tonnage, the following should be entertaining, if not useful:
Tonnage has nothing to do with the weight of your boat. It is a measure
of how much wine a vessel can carry.
The word "tun" was originally a size of a cask used to ship wine from
Spain & Portugal to England. In 1347 a tax of 3 shillings per tun was
imposed and this was called "tonnage." A ship's size became known by the
number of casks it could carry, and the word tonnage started being used
to describe a ship's size.
It was found that if you took the length x the breadth x the depth of
the hold under the deck and divided by 100 it was close to the number of
casks. That is where we get the "Measurement ton" of 100 cubic feet per
ton.
There are several kinds of tonnage: The first two are used by the tax
collector. The next two are used by designers. The fifth and sixth are
used by freight salesmen and canal operators and the last one is used by
the USCG for documenting boats.
Gross Tonnage - is the internal volume in cubic feet of the vessel
minus certain spaces above the main or "tonnage" deck, like stacks and
ventilators, which are called "exemptions" .
Net Registered Tonnage - is obtained by deducting from the gross tonnage
the volume of space that can't be used for paying cargo or passengers,
that is to say the space occupied by the engines, the crew's quarter,
the stores, etc.
Displacement Tonnage - is the actual weight of the water "displaced" by
the ship and is usually quoted in long tons of 2240 lbs.
Light Displacement Tonnage - is the weight with nothing in it.
Loaded Displacement Tonnage - is the fully loaded weight to the maximum
and is on her summer draft in salt water.
Deadweight Tonnage - is the difference between Light and Loaded
Displacement Tonnage....the actual carrying capacity of the vessel.
Panama & Suez Canal Tonnages - these are different from the internationally
accepted definitions. There used to be a lot of variations between countries and the canal owners thought they were being conned, so they came up with their own definitions.
Simplified Measurement System ((This applies in the US...I have no idea whether the same calculations are used anywhere else in the world) - The USCG decided that all this was way too much for bureaucrats to deal with for yachts so they came up with their own formula:
Take the horizontal distance between the outboard ends of the boat not
including rudders and bow sprits. Multiply that by the maximum beam outside to outside. Multiply that by the distance from the sheer line not including bulwarks
or cap rails to the outside bottom of the hull not including the keel. Add the volume of the deck house/cabin top. Multiply by .5 for sailboats and .67 for power boats.
Divide by 100.
This will give you the "Gross Tonnage". Net tonnage is 90% of gross for
sailboats and 80% for power boats.
It should be obvious to anyone who's managed to get this far that your boat's "tonnage" no longer has anything to do with anything real; it only exists in the mind of some government bureaucrat.

Thought you were a specialist in "dunnage" not tonnage!
Excellent summary of "Tonnage" though darling though you missed "Thames Measurement". What's that then clever clogs cos I could not remember the other day when asked......

well done Peggy -
but..... fill your boat full of wine casks, count them and pay your dues.
then.... fill 100 containers full of more wine casks, stack them 10 high on your deck and you really have fooled the bureaucrats !!

Google for it in plain English...
In the Google search box just type what you want; e.g:
how many lbs in a ton
gives the answer: 1 ton=2000 pounds
if you ask:
how many lbs in a tonne
the answer is: 1 tonne=2204.62262 pounds
Its fun seeing just what else it will do. You'd be surprised!!!
Cheers, Jerry

I wish I could claim credit for the knowledge behind that...but that belongs to a friend named Glenn Ashmore. I was only smart enough to save it after after he'd posted it several years ago.
