Unit Rate Calculator
Simplify any rate into a comparison to one. This tool is essential for finding the best value while shopping or calculating constant speeds and rates.
What is a unit rate?
A unit rate is a ratio that compares a quantity to exactly one unit of another quantity. Examples include price per ounce, miles per hour, or heartbeats per minute.
How do you calculate unit rate?
To find the unit rate, divide the first quantity by the second quantity. For example, if you pay $3.00 for 12 ounces, the unit rate is $3.00 / 12 = $0.25 per ounce.
Why is unit rate useful for shopping?
Unit rates (often called "unit prices" in stores) allow you to compare the value of different sized packages. A larger box may not always be the better deal if its unit price is higher than a smaller box.
What is the difference between a rate and a unit rate?
A rate is a comparison of two different units (e.g., 100 miles in 2 hours). A unit rate is that same comparison simplified so the second number is 1 (e.g., 50 miles per 1 hour).
