# Rate vs. Ratio: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on November 18, 2023

Rate is a measure of one quantity per unit of another, while ratio is a comparison or relationship between two quantities.

## Key Differences

A rate is a specific type of ratio that compares two different kinds of quantities, usually expressing how one quantity changes in relation to another. A ratio, in contrast, is a comparison between two quantities of the same kind, showing how much of one exists relative to the other.

Rates often involve time, such as speed (miles per hour) or pay (dollars per hour), showing how one quantity changes over time. Ratios, however, compare quantities directly, like the proportion of sugar to flour in a recipe, without necessarily involving time.

A rate is typically expressed with different units (e.g., kilometers per hour), emphasizing the idea of one quantity per unit of another. A ratio, on the other hand, can be expressed as a fraction, a decimal, a percentage, or with a colon, like 3:2, indicating the relative size of one quantity to another.
