Kelvin

Kelvin is a unit of measurement for temperature. It is one of the seven base units in the International System of Units (SI). The Kelvin scale is an absolute temperature scale, meaning that it starts at absolute zero, the theoretical lowest possible temperature where particles have minimal motion.

Conversion

To convert a temperature from Celsius to Kelvin, you can use the following formula:

Kelvin = Celsius + 273.15

Usage

Kelvin is commonly used in scientific and engineering applications, especially in fields such as physics, chemistry, and thermodynamics. It is also the primary temperature scale used in the study of the behavior of gases and in many other areas of science.

◂Math Worksheets and Study Guides Third Grade. Units of Measure

The resources above cover the following skills:

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.
