Scope and limitations

Absorbed energy per mass only. Gray is not interchangeable with sievert without radiation and tissue weighting. Not a medical dose calculation.

Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.

Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
