Precision and calculation record
Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.
Saved scenario
Save the current answer, then change an input to compare. This clears when you leave.
Formula and assumptions
This converter covers Nike women's tops only. It does not convert men's, children's, trouser or other brands' sizes. Enter an exact listed numeric label; for a US W size, choose the plus chart and enter the number. A chart entry can cover two labels, so the result preserves the range rather than implying an exact equivalent or guaranteed fit. US 0 appears in both XXS and XS; both are shown. Use the garment maker's measurement guide when choosing what to buy.
Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.
Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.
Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.
