alright if you walk into someplace in Paris and ask for three yards of
- 00:10
fabric well they'll probably look at you like you're nuts. [man asks McDonalds worker for fabric]

metric system. well you'll run into problems all the
- 00:23
time where you have to convert from one unit to another when dealing with
- 00:26
distances or lengths or weights. you name it. by metric system think like kilograms
- 00:33
instead of pounds and meters instead of yards. well the good news is that you
- 00:40
don't have to have all those conversions memorized. your brain has enough stuff to
- 00:45
worry about. all you really have to do is refer to a conversion chart. where
- 00:49
someone's already done the dirty work for you, [kid with messy face holds conversion chart]

- 01:07
kilometers on our handy dandy chart, or a chair and we see that one mile equals
- 01:12
about one point six oh nine kilometers. all right then we'll you can take nine
- 01:16
point six five six right there plug that into our calculator and divide by one [equation]
- 01:21
point six oh nine to get just about six miles exactly. see how cleverly you could
- 01:26
give that problem there for you no extra charge. okay so from there with
- 01:30
you whatever else particularly problem asks of us whether it's asking for a
- 01:34
rate or time or whatever. so chew on that while you're chewing on your little Big
