This worksheet helps students practice converting between liters (L) and milliliters (mL) through 12 direct conversion problems. Students will then solve four word problems to determine if each camper has enough water. Suitable for fifth and sixth graders, this worksheet complements lessons on metric measurements and provides essential practice for real-world mathematical applications.

Tell your students to think of a liter like a big water bottle. One liter is the same as 1,000 milliliters. So if you have 1 liter and want to know how many milliliters that is, multiply by 1,000 to get 1,000 milliliters. If you have milliliters and want to change them to liters, you divide by 1,000. For example, 500 milliliters is half of 1,000, so that's 0.5 liters. It's like counting coins: if you have 1,000 pennies, that's the same as 10 dollars!
