Ratio calculator:

A ratio calculator is a helpful application that helps you compare two quantities or values by expressing them as a ratio. In simpler terms, it's like a digital tool that assists you in finding the relationship between two numbers or things. For example, suppose you have five red marbles and three blue marbles. In that case, you can use a ratio calculator to figure out that the ratio of red to blue marbles is 5:3. It's beneficial when you need to make proportional comparisons or scale measurements up or down. Whether you're working with recipes, finances, or any situation where you want to understand how one quantity relates to another, a ratio calculator can do the math for you quickly and accurately. This makes it a nifty tool for simplifying complex ratios and making your calculations a whole lot easier.


  • To calculate the missing value in the ratio A: B = C : D using an online ratio calculator with the provided data, follow these steps:
  • Enter the known values into their respective fields: A = 3, B = 4, C = 600 (The value for which you want to find D)
  • Set the calculator to find the missing value, which is D in this case.
  • Click the "Calculate" or "Solve" button to obtain the value of D.
  • The result should be displayed, giving you the missing value in the ratio A: B = C : D, which, in this case, is the value of D.

Ratio scaling calculator

A ratio scaling calculator is a tool used to compare and adjust measurements or values by using ratios. In simple terms, it helps you understand and work with different quantities or numbers in a way that makes them more understandable and comparable. When you have various data points or numbers, each with its scale or range, ratio scaling helps you put them on a standard scale so you can make fair comparisons. For example, suppose you have scores from two different exams that use other grading systems. In that case, a ratio scaling calculator can help you convert them to a standard scale so you can determine which score is better or if the students performed equally. It's a valuable tool for researchers, analysts, and anyone dealing with data from different sources or formats.


Ratio calculates the scaled ratio when you have the original ratio and want to enlarge or shrink it by a particular factor; you can follow these steps:

  • Enter Original Ratio: 250: 280
  • First, you'll need to determine the scaling factor. For example, 2.5 times.
  • Multiply both parts of the original ratio (the numerator and the denominator) by the scaling factor. 250 * 2.5 : 280 * 2.5
  • Calculate the new values: like 625: 700
  • So, when you enlarge the original ratio of 250:280 by 2.5 times, you get the new ratio of 625:700 in Graph or pictorial form.
