Formula and method
This calculator uses the values you enter and applies the calculation immediately in your browser. The main output formulas are:
- Scaled amount:
originalAmount*(newServings/originalServings)
Some formulas are undefined for certain input combinations, such as division by zero, equal x-values in a slope calculation, or logarithms of non-positive numbers. In those cases the live tool reports that the result is undefined instead of displaying Infinity or NaN.
Examples
- Example: with Original ingredient amount = 2, Original servings = 4, New servings = 6, this calculator returns Scaled amount = 3.
