• Why do we need to know the metric system when we have US customary measurements?
• Here are some good reasons for learning the metric system.

1) The metric system is used almost throughout the whole world; the U.S. is one of the few exceptions.
2) Unit conversions are much easier to perform in the metric system than in the US customary system, because the metric system is based on powers of 10.
3) You will frequently encounter metric units if you take science classes such as chemistry and physics.
• This is not a question but who drink 6 pichers of tea
• um hi my name is coral why do you pick just him why not a girl
• There is a girl. Her name is Lindsay. She makes videos sometimes.
• is area height plus width times length ( h+w ) x l
• how many milliliters in a liter? I forget.
• There are 1,000 milliliters in a liter.
In other words, a milliliter is one-thousandth of a liter.
• i'm still a little confused. can someone help explain it more?
• there are 1,000 milaleters in a leter
• can someone help me understand the metric system, I don't get it and I'm struggling with the questions.
• The metric system is just another way of measuring. Here in the U.S., we use the U.S. Customary system. The metric system is used everywhere else in the world. Understanding the metric system is not that hard once you understand the unit conversions. Do not worry, you will get the hang of it.
• The area of a panel is 0.8 square meter. If the width of the panel is 1.6 meters, what is the length of the panel?
