Chemistry Unit Conversions

Vocabulary and key concepts from the lecture on chemical unit conversions and measurement comparisons.

Conversions

The process of going from one measurement unit to another to allow for a fair comparison between different properties like volume and mass.

Liters

The unit used in the lecture to measure volume, such as the water in a glass.

Grams

The unit used in the lecture to measure mass, such as the weight of an apple.

Conversion Formula

The mathematical setup used to solve conversion problems: $\text{given unit} \times \text{desired unit} / \text{given unit}$.

Conversion Factor

A number that represents a certain amount of one unit per every unit of something else, used to bridge the gap between what is given and what is being asked.

Given Unit

The starting point or the unit of measurement you currently have in a problem (e.g., $5\,grams$).

Desired Unit

The specific unit of measurement that the problem asks you to convert into (e.g., $\text{liters}$).

Relationship of Units

The specific conversion factor mentioned in the example where every $1000\,grams$ equals $1\,liter$.

Diagonal Cancellation

The step in the conversion process where the given unit in the numerator on the left divides out the matching given unit in the denominator on the right.

Calculated Result

The final answer obtained in the lecture example after dividing $5$ by $1000$, which is $0.005\,liters$.
