Vocabulary

conversion factor - multipliers that allow us to convert a quantity expressed in one kind of unit into an equivalent value expressed in another.

base unit - a fundamental unit of measurement that is defined arbitrarily and not based on other combinations of units. Examples from the SI system include the meter, kilogram, liter, second, and kelvin.

derived units - a unit created by combining base units.

Imperial system - a system of units of measurement that is primarily used in the United States and consists of units like the pound, ounce, mile, and inch.

International System of Units (SI) - a complete metric system of units of measurement used by scientists that is based on multiples of ten.

scientific notation - a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits.
