When can I use the lead-to-sale conversion result?

The result is an expected continuous volume, not a realised whole-number sale count. Rates need the same traffic source and period.

Why are some results rounded?

Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
