About Converting Units

What this skill is

Converting units teaches converting measurements within the same system from larger to smaller units (and vice versa) using multiplication or division by conversion ratios.

When children learn it

Unit conversion tables are taught in 4th and 5th grade, aligned to Common Core standards 4.MD.A.1 and 5.MD.A.1.

Teaching Tips

  • Use rule: Big to Small = Multiply; Small to Big = Divide.
  • Set up conversion ratio tables to organize steps.

Common Mistakes

  • Dividing when converting larger units to smaller units (e.g., dividing feet by 12 instead of multiplying to get inches).
  • Using wrong conversion multipliers.
