Given that there are approximately 2.1 lbs in a kilogram, how much more does a metric ton weigh than an English ton?
a) 50 lbs
b)100lbs
c) 200lbs
d) 400 lbs
e) English and Metric tons weigh the same

The answer was: B, 100 Lbs and the explanation was

A metric ton is 1000kg, or 2100 lbs. An English ton is 2000 lbs. Thus, the metric ton weighs 100 lbs more than the English ton.


I put E, because I thought a ton = 2000 lbs and converting to kg would still be weighing 200 lbs. ....
Are we supposed to have just known that a metric ton is 2100 and english ton is 2000? Would someone explain the math?

This is an unlikely conversion. Nonetheless, who says it won't potentially show up? He's just preparing you for the worst.

Trust Ari, he usually knows what he's talking about!

It showed up before on the DAT, so it's good to know. Is it likely to get tested again? Maybe not, but better to know and not need it than need it and not know it!

EDIT: Also, one metric ton is 1000 kg. (1000 kg)(2.1 lbs/kg) = 2100 lbs

An English ton is 2000 lbs.

2100 - 2000 = 100 lbs.

I guess it's semantics, but shouldn't we learn that it's 2.2lbs/Kg?

Regardless, whichever conversion units they give us is the one we must use. Always good to know the metric ton and the English ton

My dentist constantly talks about how the metric ton/English ton conversion saved him throughout clinic, and the ADA was brilliant for using that as a measure of competency for dental school!!!
