Units of Measure
Units of measure are used to quantify different attributes such as length, weight, volume, time, and more. Different units are used to measure different attributes.
Common Units of Measure
Some common units of measure include:
- Length: meters (m), centimeters (cm), inches (in), feet (ft)
- Weight: grams (g), kilograms (kg), ounces (oz), pounds (lb)
- Volume: liters (L), milliliters (mL), gallons (gal), quarts (qt)
- Time: seconds (s), minutes (min), hours (hr), days (d)
Converting Units
Sometimes it is necessary to convert units from one form to another. For example, converting from meters to centimeters or from grams to kilograms. Conversion factors are used to perform these conversions.
Measuring Tools
Various measuring tools are used to measure different attributes, such as rulers and tape measures for length, scales for weight, beakers and measuring cups for volume, and clocks for time.

Measurement (NCTM)
Understand measurable attributes of objects and the units, systems, and processes of measurement.
Understand such attributes as length, area, weight, volume, and size of angle and select the appropriate type of unit for measuring each attribute.
Understand the need for measuring with standard units and become familiar with standard units in the customary and metric systems.
Understand that measurements are approximations and how differences in units affect precision.
Apply appropriate techniques, tools, and formulas to determine measurements.
Select and apply appropriate standard units and tools to measure length, area, volume, weight, time, temperature, and the size of angles.
Connections to the Grade 3 Focal Points (NCTM)
Measurement: Students in grade 3 strengthen their understanding of fractions as they confront problems in linear measurement that call for more precision than the whole unit allowed them in their work in grade 2. They develop their facility in measuring with fractional parts of linear units. Students develop measurement concepts and skills through experiences in analyzing attributes and properties of two-dimensional objects. They form an understanding of perimeter as a measurable attribute and select appropriate units, strategies, and tools to solve problems involving perimeter.
