The Imperial and US customary units comparable to the tonne are both spelled ton in English, though they differ in mass.

In the United States, the unit was originally referred to using the French words millier or tonneau, but these terms are now obsolete. The spelling tonne pre-dates the introduction of the SI in 1960 it has been used with this meaning in France since 1842, when there were no metric prefixes for multiples of 10 6 and above, and is now used as the standard spelling for the metric mass measurement in most English-speaking countries.

#Meter tonne full
A full tun, standing about a metre high, could easily weigh a tonne. Old English and Old Frisian tunne, Old High German and Medieval Latin tunna, German and French tonne) to designate a large cask, or tun. Ton and tonne are both derived from a Germanic word in general use in the North Sea area since the Middle Ages (cf. Both terms are acceptable in Canadian usage. In the United States, metric ton is the name for this unit used and recommended by NIST an unqualified mention of a ton almost invariably refers to a short ton of 2,000 pounds (907 kg), and tonne is rarely used in speech or writing. In Australia, the common and recommended pronunciation is / t ɒ n/. In the US and UK, tonne is usually pronounced the same as ton ( / t ʌ n/), but the final "e" can also be pronounced, i.e. In English, tonne is the established spelling alternative to metric ton. If describing TNT equivalent units of energy, one megatonne of TNT is equivalent to approximately 4.184 petajoules. For example, T, MT, mT, Mt and mt are the SI symbols for the tesla, megatesla, millitesla, megatonne (one teragram), and millitonne (one kilogram) respectively. Use of minuscule letter case is significant, and use of other letter combinations can lead to ambiguity. It is a symbol, not an abbreviation, and should not be followed by a period. Its use is also official for the metric ton in the United States, having been adopted by the United States National Institute of Standards and Technology (NIST). With our example of 2 tonne at 3 metres, if the load or sling length causes the hook to be so high that the inner boom cannot be used for the lift, then probably an 8 tonne metre crane would be the size required.Ī winch rope crane will give a vertical lift as seen in Figure 2 (therefore no increase in radius), so this consideration is not applicable to UNIC & Cobra telescopic boom cranes fitted with winches.The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879. The resulting increase in the radius can be substantial and is often sufficient to over pressurize the luff rams and to activate the overload protection (if fitted) which may prevent the crane moving into the required position. The operator may not get sufficient hook height to clear the base of the load over the tray body. In this configuration, only the outer boom can be raised. To handle a high load of near crane capacity, the inner boom must be vertical (or near to vertical), and the outer boom pointing down, with the hook above the centre of the load. You would need a crane rated at 6 tonne metres or better to do the job BUT it is important to consider the physical size of the load you are lifting. But with high or long slung loads, this calculation can lead to an embarrassment! If we say that we need to lift 2 tonne at 3 metres, we would look for a 6 tonne metre crane. Caution: Heavy (in close) lifts have a complication.
