The Unit Rate Calculator helps you break down any “per” value like price per item, distance per hour, grams per serving and gives you the precise rate for each line. Whether you’re trying to compare deals at the store or figure out how fast something’s moving, this tool handles it for you. You just paste in something like 10 dollars / 2 items, and it instantly spits out 5 dollars per item. It works with any two-part expression that follows a value / value format and automatically detects the units involved.
Everything updates in real time, right in your browser. No math needed. No page reloads. Just fast results with smart formatting. You can even control how the output looks round the results, show or hide the unit labels, or skip blank lines completely. It’s all in your hands.
How to Use:
- Paste or type lines like
300 miles / 5 hours
or12.5 USD / 3 kg
into the Input Text box. - Use the Options section to:
- Auto Detect Rate: Uses what’s written (e.g. dollars/items).
- Force Per Unit: Always treat the rate as “per one unit”.
- Force Per Time: Useful for things like speed (distance per hour).
- Use the toggle switches to:
- Round results (on by default)
- Show unit label like
5 dollars/item
- Trim empty lines
- Output updates automatically. Use the buttons to copy, export, or reset.
What the Unit Rate Calculator can do:
This tool parses every line for simple ratio-style expressions like A / B and calculates the result. If both values are present and numeric, it divides the first by the second and appends the correct unit label if you want. You can force the behavior toward specific patterns (like “per time”) if your input isn’t clear. It handles edge cases well skips bad lines, avoids dividing by zero, and respects whatever units you used. Whether you’re doing shopping math, nutrition planning, or general data cleanup, this tool just works.
Example:
Input:
10 dollars / 2 items
300 miles / 5 hours
100 grams / 4 servings
Mode: Auto Detect Rate
Toggles: Round ON, Show unit ON
Output:
5 dollars/items
60 miles/hours
25 grams/servings
Common Use Cases:
Trying to find which product is cheaper per unit? Want to figure out how many miles per hour something is going based on a trip? This calculator takes those ratio-style lines and gives you clean, simple results. It’s great for budgeting, trip planning, recipes, or anything that needs a “per” comparison. You control the output, it just handles the math.
