Conversions can be tricky, but with this easy guide, students can tackle measurement questions confidently. From centimeters to inches and kilometers to miles, these quick examples and simple explanations will make math and science more fun!
How to Think About Measurement Conversions
Understanding conversions is all about seeing the relationship between two units of measurement. Here’s a simple framework for teaching kids how to approach them:
Know the Rule: Memorize the basic conversion factor (e.g., 1 inch = 2.54 cm).
Think Visually: Use real-world examples, like the length of a paperclip or a mile-long walk.
Practice Makes Perfect: Work through examples to reinforce the concept.
Let’s dive into some conversion examples and rules!

28 mm ≈ 1.1 inches
1,000 mm (1 m) ≈ 39.37 inches
81 mm ≈ 3.2 inches
0.49 mm ≈ 0.02 inches
Celsius to Fahrenheit
Basic Rule: F=(C×9/5)+32F=(C×9/5)+32
Examples:
0°C = 32°F
44°C ≈ 111°F
72°C ≈ 161.6°F
0.01°C ≈ 32.02°F
How Many Weeks in a Year?
Basic Rule: 1 year = 52 weeks
Examples:
1 year = 52 weeks
2 years = 104 weeks

Examples:
0.5 gallons = 64 ounces
2 gallons = 256 ounces
Inches to Centimeters
Basic Rule: 1 inch = 2.54 cm
Examples:
0 inches = 0 cm
12 inches = 30.48 cm

Examples:
2 cups = 16 ounces
0.5 cups = 4 ounces
Kilometers to Miles
Basic Rule: 1 km ≈ 0.621 miles
Examples:
5 km ≈ 3.1 miles
10 km ≈ 6.2 miles
