Measurements

Scientific Measurement

A quantity and unit used to report a scientific measurement. The quantity represents the magnitude, while the unit indicates the type and scale of the measurement.

Scientific Notation

A method used to simplify large numbers. It consists of a decimal between 1 and 10 with a single digit to the left of the decimal, followed by any additional numbers. It also includes a multiplier, where 10 is raised to a given power by the subscribed component.

Units

The types of measurement used in the metric system. They include base units such as meter (m) for length, liter (L) for volume, and gram (g) for mass. Units can be modified using prefixes to indicate multiplication or division by factors of 10.

Prefixes

Indicators used to modify base units by multiplying or dividing them by factors of 10. Some prefixes create multiples of the original unit, such as kilo- (1 kilogram = 1,000 grams), while others create fractions of the original unit, such as centi- (1 centimeter = 1/100 of a meter).

Quantity

The magnitude of a measurement, which can be represented in two different ways:standard notation (the normal number form) or scientific notation (using a decimal between 1 and 10 with a multiplier raised to a given power).
