Ton is imperial (1 ton = 2000 lbs), Tonne is metric (1 tonne = 1000 kgs = 2200 lbs approx.)
1 tonne = 1.1 ton
We are in Canada; therefore, we sell by the metric tonne! (Some contractors sell by the ton. Be cautious if comparing prices, as you are receiving 10% less. If buying by the ton, just ask if metric tonne or imperial ton. Sorry for the confusion, but we do like metric.)
