Lesson 6: Convert Metric Units of Mass

In this Grade 5 lesson from enVision Mathematics Chapter 12, students learn to convert metric units of mass among milligrams (mg), grams (g), and kilograms (kg) by multiplying when converting from larger to smaller units and dividing when converting from smaller to larger units. Students apply the base-10 relationships (1,000 mg = 1 g and 1,000 g = 1 kg) to solve real-world problems and compare masses across different units.

Section 1

Metric Prefixes for Mass

Property

Metric prefixes describe a power of 10 relationship with a base unit. For mass, the base unit is the gram (g).

  • kilo- (k) means 1,000 times the base unit.
  • milli- (m) means 11,000\frac{1}{1,000} of the base unit.

Examples

Section 2

Comparing Metric Masses

Property

To compare masses with different units, convert one of the measurements so that both masses are in the same unit. Then, compare the values.

A kg vs. B g    (A×1,000) g vs. B gA \text{ kg} \text{ vs. } B \text{ g} \implies (A \times 1,000) \text{ g} \text{ vs. } B \text{ g}
