Metric and customary conversion reference

Metric and Customary Conversion Reference Sheet

Converting between metric and customary units can be tricky for students, especially when math and science concepts start overlapping. This Metric & Customary Conversion Reference Sheet is designed to give students a clear, reliable place to check common conversions without interrupting their work or losing focus.

This printable includes side-by-side tables for length, mass (weight), volume, and temperature, making it easy to compare units like inches and centimeters, pounds and kilograms, cups and milliliters, as well as Celsius, Fahrenheit, and Kelvin. Everything is organized in a clean, easy-to-read format that works well as a classroom reference, homeschool resource, or study aid.

Teachers often use conversion charts like this as desk references, binder inserts, or wall anchors, while homeschool families appreciate having a single page that covers the most commonly used units in U.S. classrooms. The minimalist design keeps distractions low and makes the sheet printer-friendly for everyday use.

This reference sheet is especially helpful for:

  • Middle school math and science
  • Homeschool lessons and independent practice
  • Lab work and measurement activities
  • Test prep and quick unit checks

Download the printable and keep it handy whenever students need a fast, accurate conversion reference.
