Key Concepts

Unit Conversion

Unit conversion is the process of converting a quantity expressed in one set of units to another set of units. This involves using conversion factors, which are ratios that express how many of one unit are equivalent to another. For example, to convert milligrams to grams, one would use the conversion factor that 1 g = 1000 mg.

Metric System

The metric system is a decimal-based system of measurement used worldwide, which includes units such as meters, liters, and grams. It is organized in powers of ten, making conversions straightforward. Understanding the prefixes, such as milli- (10^-3) and pico- (10^-12), is essential for converting between different metric units.

Dimensional Analysis

Dimensional analysis is a mathematical technique used to convert units by multiplying by conversion factors that cancel out unwanted units. This method ensures that the final answer is expressed in the desired units. It is particularly useful in chemistry for converting between different measurements, such as mass and volume.
