Convert kilograms to grams and liters to milliliters with this free metric mass and capacity worksheet. The practice page contains eight numbered questions, with a separate answer page so learners can attempt the work before checking. It is designed for focused practice after the underlying idea has been introduced, rather than as a timed test or a placement assessment.
How to work through the questions
Use 1000 grams per kilogram and 1000 milliliters per liter. Multiply each given value by 1000. Begin by identifying the information supplied and the quantity you need to find. Write at least one intermediate step beside each question; the working is often more useful than a final answer when you are deciding what to review.
A first-question check
The first prompt is: Convert 2.5 kg to g and 3.25 L to mL. The checked result is 2500 g; 3250 mL. Use the method above to explain how the given information leads to that result. Then cover the key and solve the remaining questions independently.
What to watch for
Label the result in grams or milliliters to match the quantity; these units are not interchangeable. If an answer differs from the key, compare one step at a time. Mark whether the issue came from reading the prompt, choosing an operation, calculating, or writing the units. Correct that step and retry the question without copying the answer.
