Common issues

The result is undefined or infinite.

Make sure the value used as the divisor is not zero and that every known field contains a number.

The proportion is numerically correct but the real quantity is wrong.

Convert all inputs to compatible units before calculating and keep the unit with the result.

How to interpret the result

Use x only after confirming the proportion order, compatible units, cross-products, and rounding precision.
