what we're going to do in this video some examples converting between leaders and milliliters and just as a reminder milli means one thousandth so a milliliter is one thousandth of a liter or another way to think about it one liter is one thousand milliliters so given that how many milliliters would seven liters be pause the video and think about that well if one liter is one thousand milliliters then seven liters would be seven thousand milliliters and what about 18 liters pause the video and think about it well that would be 18,000 18,000 milliliters so ever however many liters you've got it would be a thousand times as many milliliters because each milliliter is one thousandth of a liter let's do some more examples so here says blank milliliters equals 15 liters pause the video again see if you can figure this out well remember every liter is a thousand milliliters so 15 liters would be 15 thousand milliliters remember if you have a smaller unit and here you're smaller by a factor of a thousand the number that you would need of it to have the same as the large unit would be larger so you have a smaller unit so you have a larger number here let's do one more example compare using greater than less than or equal to so nine liters how does that compare to ninety milliliters pause this video and try to answer it for yourself well how many milliliters is nine liters nine liters is the same thing as nine thousand milliliters and nine thousand milliliters is clearly greater than ninety milliliters so what you want to do in a problem like this is convert both to milliliters nine thousand milliliters that's what nine liters is that's nine thousand milliliters that's going to be greater than ninety milliliters
