A pound is a smaller unit of weight, so you could be more precise using it.
A ton is just two-thousand pounds.
9 tons is more.
Depends on how deep the ponds are.
5 tons
ponds
4000 pounds = 2 tons
A ton - a metric ton to be more precise - has a million grams.
3/8ths
nope, 9 tons and 18000 ponds equal the same ammount
No. Those are equal weights.
2 t(US) = 4000 lb
Unfortunately, there is not a simple answer: it depends on what you mean by "more precise". Both have three significant figures and to that extend they are equally precise. However, the maximum possible percentage errors in the two measurements are approximately 100*0.05/42.3 = 0.12% and 100*0.05/35.6 = 0.14%, respectively. On that basis, 42.3 ounces is more precise in relative terms. Also, the measurement units are smaller for 42.3 ounces so in absolute terms the measurement is more precise.
On ton is 2,000 pounds so just divide 18,000 by 2,000 or 18 by 2 and you discover that there are 9 tons in 18,000 pounds
