Students fix three metric errors — 3 km given as 300 m, 5,000 g as 50 kg, and 4 L as 400 mL. Part B has four fill-in-the-blank questions about meters to centimeters, kilograms to grams, and milliliters to liters. Part C has two short-answer questions about 2 liters in milliliters and why the metric system simplifies conversions.
Identifying metric errors reinforces that the conversion factor is always 1,000 — not 10 or 100 — for kilometer, kilogram, and liter.

Measurement Conversions
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
3 kilometers = 300 meters because 1 kilometer equals 100 meters.
Rewrite: 3 kilometers = 3,000 meters because 1 kilometer equals 1,000 meters and 1,000 × 3 = 3,000.
2. Fix the sentence:
5,000 grams = 50 kilograms because you divide by 100.
Rewrite: 5,000 grams = 5 kilograms because you divide by 1,000 and 5,000 ÷ 1,000 = 5.
3. Fix the sentence:
4 liters = 400 milliliters because there are 100 milliliters in a liter.
Rewrite: 4 liters = 4,000 milliliters because there are 1,000 milliliters in a liter and 1,000 × 4 = 4,000.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 1 meter = 100 centimeters
2. 2 kilograms = 2000 grams
3. 7,000 milliliters = 7 liters
4. 500 centimeters = 5 meters
Part C: Short Answer
Answer each question in one or two complete sentences.
1. A water bottle holds 2 liters. How many milliliters is that? Show your work.
Since 1 liter equals 1,000 milliliters, multiply 2 by 1,000 to get 2,000 milliliters.
2. How does the metric system make converting units easier than the customary system?
The metric system uses powers of 10, so you just move the decimal point or multiply and divide by 10, 100, or 1,000.
Measurement Conversions
★ Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1) Fix the sentence:
3 kilometers = 300 meters because 1 kilometer equals 100 meters.
Rewrite: 3 kilometers = 3,000 meters because 1 kilometer equals 1,000 meters and 1,000 × 3 = 3,000.
2) Fix the sentence:
5,000 grams = 50 kilograms because you divide by 100.
Rewrite: 5,000 grams = 5 kilograms because you divide by 1,000 and 5,000 ÷ 1,000 = 5.
3) Fix the sentence:
4 liters = 400 milliliters because there are 100 milliliters in a liter.
Rewrite: 4 liters = 4,000 milliliters because there are 1,000 milliliters in a liter and 1,000 × 4 = 4,000.
