Lesson 6: Converting metric units

Metric units of volume review (L and mL)

Review the size of liters and milliliters and how to convert between the two.  Then, try some practice problems.

Metric units of volume

Volume measures capacity. For example, the volume of a bowl is the amount of space inside the bowl or how much water, for example it would take to fill the bowl.
In the metric system of measurement, the most common units of volume are milliliters and liters.

How big is a milliliter?

A single raindrop contains about $1$ milliliter of liquid:

How big is a liter?

This bottle contains about $1$ liter of liquid:
Problem 1A
Identify the most reasonable unit to measure the volume of a neighborhood swimming pool.

Converting liters to milliliters

To convert to $\text{milliliters}$ we multiply the number of $\text{liters}$ by $1,000$.
Example:

Converting milliliters to liters

To convert $\text{milliliters}$ to $\text{liters}$ we divide the number of $\text{milliliters}$ by $1,000$.
Example:
Problem 2A
Convert.
$49$ liters $=$
milliliters

• how many liters are there in 10.000
• 10,000mL = 10L
10ml = 0.01mL
• United States customary units form a system of measurement units commonly used in the United States and U.S. territories since being standardized and adopted in 1832. The United States customary system developed from English units which were in use in the British Empire before the U.S. became an independent country.
• why is ml is smaller then l
• In the metric system, the prefix m stands for “milli”, which means “1/1,000 of”. So 1 ml (milliliter) is only 1/1,000 of 1 l (liter). Therefore, 1 ml is smaller than 1 l.
• This is kind of a weird question ok. If numbers can go infinite, like for example, 10,100,1000... and so on forever. And we can name them like, ten, hundreds, thousands like that. Then if it kept going. How are we going to name them infinitely?
• We don't, it's impossible because the numbers go on INFINITELY
• I am happy, 2/3 correct lol, thats the best ive gotten all day. T-T
• Pounds to Kilograms: 1 kg = 2.2 lb.
Gallons to Liters: 1 gal = 3.785 L.
Feet to Meters: 1 foot = 0.305 m.
Miles to Kilometers: 1 mi = 1.61 km.
Cups to Milliliters: 1 c = 240 mL.
Inches to Centimeters: 1 in = 2.54 cm.
Ounces to Grams: 1 oz = 28.3 g.
• Re: Converting measurement. I see questions that can be answered if you know KHDUDCM (king henry story) but where can you find divide or multiply by a 1000 each time lesson please? I do not mind which grade it is as I am pretty good with the King henry story now but have just discovered i dont understand the maths behind it really.
45 mL= 1000 45
=45÷1000=0.045
