Unit Rate Calculator
Use our unit rate calculator to calculate unit rate quickly from two values. Includes unit rate calculation, how to figure out unit rate, finding unit rate examples, calculate unit rates with fractions, and how to find the unit rate from a graph.
What is a Unit Rate?
A unit rate is a rate where the second quantity is 1 unit. It tells you “how much per 1” (for example, dollars per 1 item, miles per 1 hour, or cost per 1 ounce).
If you’re asking what’s unit rate or what is a unit rate, it’s the simplest form of a ratio that makes comparison easy.
This unit rate calculator finds the unit rate by dividing one quantity by another, so you can compare prices, speeds, and conversions.
Unit Rate Formula
To calculate unit rate, divide the first quantity by the second quantity. The result is “per 1” of the second quantity.
Interpreted as “a per 1 b” (for example, dollars per 1 item).
Divide total cost by number of items.
Unit rate works the same way with fractions.
How to Use the Unit Rate Calculator
- 1
Enter a (the total amount).
- 2
Enter b (the number of units).
- 3
The calculator computes a ÷ b.
- 4
Read the result as the unit rate: “a per 1 b.”
Frequently Asked Questions
Divide the total amount by the number of units: unit rate = a ÷ b.
Put the quantity you want “per 1” on top, then divide by the number of units on the bottom.
A unit rate is a rate expressed per 1 unit of something, like miles per 1 hour or dollars per 1 item.
The same rule applies: divide. Example: (3/4) ÷ 2 = 3/8 per unit.
No. You can keep the answer as a fraction or convert to a decimal if you prefer.
If the graph is linear, unit rate is the slope: rise ÷ run (change in y divided by change in x).
It means the rate is expressed per 1 unit of the denominator, like $4 per 1 item.
It calculates unit rate by division. You can use it as a quick helper for comparing conversion rates (like cost per ounce).
Comparing prices, speeds, wages, fuel efficiency, and any situation where “per 1 unit” makes comparisons easier.
