Grades 6–7AlgebraGuided journey: Discover, Learn, Practice, Apply

A measurement is a number with a unit. Learn the customary units (inches, pounds, gallons) and the base-ten metric system (meters, grams, liters), then convert within and between them by multiplying by a unit rate, plus time and the Celsius-Fahrenheit link. Aligned to CCSS 6.RP.A.3 (convert measurement units using ratio reasoning) and 7.RP.A.1.

What you’ll learn

A measurement is a number and a unit; the unit decides what the number means.
Customary units are linked by fixed facts (12 in = 1 ft); metric units scale by powers of 10.
Convert by multiplying by a unit rate arranged so the old unit cancels.
Between systems, use an approximate bridge like $1 \text{ mi} \approx 1.61 \text{ km}$ .
Fahrenheit and Celsius connect through $F = \frac{9}{5}C + 32$ .
