• is there anything like a ton in the metric system?
• Good question!

A regular ton is an English (U.S.), non-metric unit. There is a metric ton called a tonne, which is 1,000 kilograms (or equivalently 1 million grams, or 1 megagram). One tonne is approximately 1.1 regular tons.

• So it would be accurate to call a liter a 'cubic decimeter' just like people sometimes measure things as being measured in cubic centimeters, right?
• Yes, that is correct!

Since there are 10 centimeters in a decimeter, there are 10^3 = 1000 cubic centimeters in a cubic decimeter.
Since a milliliter is defined as a cubic centimeter, we conclude that a cubic decimeter is 1000 milliliters, which equals a liter!

Have a blessed, wonderful day!

• at why are there so many measurements and most of them are not used as much as others.
• He's just giving examples of measurements
• I want to know why a milliliter is 1000 liters and not 1000000 liters.
• The prefix "milli-" represents 1 thousandth.
So 1 "milli"liter is 1/1000 liter, not 1000 liter (also not 1 million liter).
• I think they spell liter in america like this "liter" but in my country you say "litre".
• how much mililiters are in 9.7 liters.
