Geometric Mean of Two Numbers Calculator
Geometric Mean of Two Numbers is intended for the specific statistics task described by its name. Enter first positive number, second positive number to calculate a result expressed in value. The formula works entirely in your browser and needs no account or external API. Both values must be positive. This estimate is useful for comparing scenarios when the supplied measurements follow the stated assumptions.
How to use this calculator
- Measure first positive number in the units indicated on the input label.
- Enter Second positive number.
- Read the value result, then compare alternative inputs to evaluate your own situation.
Geometric Mean of Two Numbers formula
Math.sqrt(a*b) (value).
- The expression Math.sqrt(a*b) combines First positive number, Second positive number. Follow the units on each input: the answer is expressed in value.
- Both values must be positive.
Worked examples
Worked example: Geometric Mean of Two Numbers
Use these sample measurements: First positive number = 4, Second positive number = 9.
Compute Math.sqrt(a*b).
Using the example inputs, the result is 6 value. Use this value to verify the formula before changing the measurements.
Understanding the result
Interpret the output as value; it is not a measurement taken directly from a physical system.
Both values must be positive.
Important notes
Both values must be positive.
Review the input units, any required legal or engineering rules, and unusual edge cases before acting on this estimate.
Frequently asked questions
What does Geometric Mean of Two Numbers calculate?
It evaluates Math.sqrt(a*b) to produce value from the measurements you enter. For the example values shown, the result is 6 value.
Which assumptions matter most?
Both values must be positive.
Can I compare two scenarios?
Yes. Enter another set of measurements in the same units and compare the two outputs.
