Ratio Calculator – Easily Calculate Ratios Online

Have you ever needed to compare quantities or split ingredients, money, or materials in a specific proportion? Maybe you’re cooking and the recipe calls for a ratio, or you’re in business trying to divide profits, or in school solving math problems. Figuring out ratios manually can be tricky, especially if numbers aren’t simple. That’s where a Ratio Calculator comes in handy. With this free online tool, you can calculate, simplify, or compare ratios in seconds, saving time and avoiding errors.

Why Ratios Matter

Ratios are everywhere in daily life and work:

• Cooking and Baking: Adjusting recipes to serve more or fewer people.
  
• Business & Finance: Splitting investments, profits, or costs proportionally.
  
• Education: Understanding proportions in math, science, and statistics.
  
• Engineering & Construction: Mixing materials or scaling dimensions accurately.
  

A ratio calculator ensures accuracy, whether you’re a student, professional, or home cook.

What You Enter in the Calculator

A typical ratio calculator requires:

• Two or more numbers: The quantities you want to compare.
  
• Optional simplification: Reduce the ratio to the smallest whole numbers.
  
• Scaling factor (optional): Find equivalent ratios with a different total.
  

For example, if you want to mix paint in a 3:5 ratio, you can quickly find out how much of each color to use for any total volume.

How the Ratio Calculator Works

Here’s the step-by-step process:

1. Input numbers: Enter the quantities you want to compare. For example, 20 and 50.
   
2. Simplify the ratio: The calculator finds the greatest common divisor (GCD) to reduce the ratio.
   
   • Example: 20:50 → divide both by 10 → 2:5.
     
3. Optional scaling: Multiply each part by a factor to adjust the total amount.
   
   • Example: 2:5 scaled by 10 → 20:50.
     
4. Display results: You get the simplified ratio and can use it for calculations, recipes, or sharing proportions.
   

Example

Suppose you have 120 ml of orange juice and 180 ml of water and want to express it as a simple ratio.

1. Enter 120 and 180 in the calculator.
   
2. The calculator finds the GCD (60).
   
3. Divide both numbers by 60 → 2:3.
   

So the juice-to-water ratio is 2:3, which means for every 2 parts juice, you need 3 parts water.
