Which measurement is larger?

1) 334 m or 1 cm

2) 3.4 cm or 30 mm

3) 1 km or 1000 cm
 
You don't need, and shouldn't, use google to do this. It is an exercise in unit conversions. Just write both numbers of each set with the same units...

334 m = 33400 cm (because 100 cm in a m) OR
1 cm = 0.01 m (same idea)

When they are the same units, then it is a matter of just saying which is larger.

If they get tricky, convert BOTH numbers to a unit that is DIFFERENT FROM THE QUESTION.... eg. for 3), it might be tougher to figure out how many cm in a km, but you can convert both of those to m, and then do your comparison.

WHY NOT?
Say someone does not know 1 mile = 5280 feet;
is there a better/quicker way than using google?
It's quicker than using a dictionary :idea:

The use proposed for Google was to have Google provide the solution. I think the tutor's point was that the student should have memorized the information on the units (since it is being studied in class), and then done the conversion by moving the decimal point the appropriate number of places.

Since Google won't likely be available on the test, it would probably be better if the student memorized the required information, instead of having Google complete the homework assignment.

Just my opinion, of course; I could be wrong....

Yes, Stapel got my meaning... Google will get you the answers, but it's not going to teach you HOW to get the answers. It's like when I was in high school, we were allowed calculators for homework etc, but come test time, you'd better know how to do it on your own.

Unit conversions are NOT such a difficult concept that students should have to rely on someone/something to tell them the answers. Furthermore, when they get further along into things such as physics (even elementary physics), keeping track of units and expressing things in equivalent terms is VERY important.

There are reasons for exercises such as these... reasons that are defeated by using Google, as you suggest.
