• what if you comparing 7 quarts and 3 tons?
• Well, quarts are a measurement of volume/space, and tons are a measurement of weight, so they aren't exactly interchangeable. A quart of strawberries could weigh a different amount than a quart of rocks. You'd have to find out how much 7 quarts of the item you're measuring is in pounds or tons, then do the math. :)
• How do you convert US customary to metric system
• Convert 100 m to cm with solution
• how many grams eqeal a kilogram
• The word "kilo" means 1000.

1 kilogram
= 1000 x 1 gram
= 1000 grams
So 1 kilogram equals 1000 grams

You can do the same thing anytime you see kilo - just multiply the unit x 1000. For example, convert 25 kilometers to meters:

25 kilometers
= 1000 x 25 meters
= 25,000 meters
So 25 kilometers equals 25,000 meters

Hope this helps!
• why does milli mean 1out of 1,000?
• How many grams are in a liter?
• 1 gram is a measurement of mass and 1 liter is a measurement of volume. There are things that takes up more space (large volume) but are quite light (small mass), such as the gas helium. 1 liter of helium weighs 0.18 grams. In comparison, 1 liter of the metal mercury weighs about 14000 grams.
