SumHexa — Calculate anything.

Simple and weighted average

Calculate the arithmetic average of a list, with or without weights.

Changing modes clears your inputs and result.

Separate numbers with a semicolon or line break (1 to 1,000 values). A dot or comma can be used as the decimal separator, without thousands separators. Values remain in your browser. Each value has equal weight. Example: 10; 12; 14 → 12.

Your inputs stay in your browser. Displayed results are rounded to a maximum of 12 significant digits.

Weighted average

Formula: Σ(x × w) / Σw

Separate numbers with a semicolon or line break (1 to 1,000 values). A dot or comma can be used as the decimal separator, without thousands separators. Values remain in your browser. One weight per value, in the same order. Weights are non-negative and their sum must be positive. A zero weight excludes the value. Example: values 10; 20, weights 1; 3 → 17.5.
