Answer 1

18.75*2000=?

Answer 2

How many pounds in a ton?

Answer 3

2000 lbs in one ton

Answer 4

1 ton equals 2000 lbs
18.75* 2000= 37,500lbs

Answer 5

A ton is defined as different amounts in different parts of the world and in different contexts. Whichever value you're supposed to use for 1 ton, multiply it by 18.75.

Answer 6

... its mostly standardized because he is asking lbs.

Answer 7

37500

Answer 8

yep

Answer 9

Ok, since you know 1 ton = 2000 lb, then you know that to convert from tons to pounds you need to either multiply by 2000 or divide by 2000, right? How do you know which operation to do?

Answer 10

from tons to pounds you multiply
from pounds to tons you divide

Answer 11

Since 1 ton = 2000 lb, that means a certain weight is a much higher number of pounds than tons. If you multiply 18.75 by 2000, you get a much higher number than 18.75. that's why you need to multiply.

Answer 12

@Nogarenshi
You are correct, of course, but the question is how do you get someone to figure it out if he forgets?

Answer 13

for example they give you tons and you are asked to give pounds. Assuming you know the ratio 2000 lbs=1 ton. you can think that there are 2000 lbs in 1 ton. Ask yourself how many tons do the give you. Once you have that you know you have to multiply to get pounds \[tons*\frac{ lbs }{ tons }=lbs\]

Answer 14

the tons cancel out leaving only lbs

Answer 15

That, of course, is dimensional analysis, which is the best way of doing unit conversions.

Answer 16

this is mainly something that you either have to memorize or figure out from the word play but otherwise dimensional analysis is the next best thing

Answer 17

The reason dimensional anaylisis works is that since
1 ton = 2000 lb, dividing both sides by 1 ton, you get
1 = (2000 lb)/(1 ton), and dividing both sides by 2000 lb, you get
(1 ton)/(2000 lb) = 1
Since the conversion factors equal 1, they do not change a number when you multiply by them. It onlt changes the units.

Answer 18

exactly all it is is conversion of units nothing more and nothing less.
