Conversion mode preserves the approximate physical dimension implied by the pattern counts while substituting the actual measured gauge. Here the pattern states 18 stitches and 24 rows per reference distance, uses 96 stitches and 120 rows, while the actual swatch measures 21 stitches and 30 rows over the same distance.
Recover the intended pattern dimensions
The pattern width is 96 divided by 18 reference groups, giving 16/3 reference lengths. At a 10 cm reference that is 160/3 cm, about 53.33 cm. The pattern height is 120 ÷ 24 × 10 cm, exactly 50 cm. These dimensions are the target preserved by conversion.
Actual gauge gives 112 stitches and 150 rows
For stitches, multiply 96 by actual 21 and divide by pattern 18: the exact raw result is 112. For rows, multiply 120 by actual 30 and divide by pattern 24: the raw result is 150. No decimal approximation is required at this stage.
Apply multiples six and four
A stitch multiple of six brackets 112 with 108 and 114; nearest is 114 because it is two away rather than four. A row multiple of four brackets 150 with 148 and 152. The distances tie, so the deterministic upper rule chooses 152 rows.
Check the achieved converted size
At 21 stitches per 10 cm, 114 stitches produce 380/7 cm, about 54.29 cm, slightly wider than the intended 53.33 cm. At 30 rows per 10 cm, 152 rows produce 152/3 cm, about 50.67 cm. These differences are the visible cost of satisfying the selected multiples.
