0.6667 is the example result. Read it using the units and relationship stated below.

Result = (([First value]) ÷ ([Second value]))
Purpose

Ratio uses first value, second value.

Preserving the meaning of a conversion or working record

For ratio, the relationship is Result = (([First value]) ÷ ([Second value])). The amount depends on the supplied first value, second value, rather than a live market price or a value imported from another record. A conversion is useful when the source value and unit remain traceable. Dates, elapsed time, percentages and ratios each have their own convention. Rounding can change a schedule or quantity when the output is copied into another system.

What the model includes

Result = (([First value]) ÷ ([Second value])) Use the format shown beside the input and keep both the original and converted value. A ratio is not automatically a percentage; a calendar-day difference is not automatically a working-day count. Record the convention before comparing results. Check the result against the task being performed. An arithmetic answer does not select a business policy, a service-level agreement or a calendar rule that the page has not implemented.

Example with the supplied inputs

First value: 2; Second value: 3. Result: 0.6667. The values are illustrative.

Compare one changed input

First value changes from 2 to 2.2. The result becomes 0.7333. All other inputs remain fixed.

Calculation rule

Formula

Result = (([First value]) ÷ ([Second value]))

Inputs and output

Example inputs and entry conventions
Input Example value Entry convention
First value 2 Use the source quantity represented by first value. Keep the counted population fixed and avoid mixing a unit value with a period total.
Second value 3 Use the source quantity represented by second value. Keep the counted population fixed and avoid mixing a unit value with a period total.

Output: 0.6667 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.

How to use the page

STEP 01

Collect the inputs

Gather First value, Second value. Use one period and the units shown in the form.

STEP 02

Run the calculation

Enter the values and select the action. The calculation rule above explains how the inputs produce the result.

STEP 03

Compare a scenario

Change First value on its own, keeping the other inputs fixed. Read both results before changing another assumption.

Worked example

With the example inputs listed above, the result is 0.6667.

Change First value from 2 to 2.2 while keeping every other value fixed. The result becomes 0.7333. This comparison isolates that input; it does not forecast how other variables will respond.

Check the stated formula, units and limits before using the result in a decision.

Calculation and source notes

Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
