Formula (extracted text)

$StitchGauge = {SwatchStitches \over SwatchWidth}$ $RowGauge = {SwatchRows \over SwatchHeight}$

Formula (extracted text)

$TotalStitches = DesiredWidth \times StitchGauge$ $TotalRows = DesiredHeight \times RowGauge$

Formula (extracted text)

$SwatchArea = SwatchWidth \times SwatchHeight$ $ProjectArea = DesiredWidth \times DesiredHeight$ $YarnDensity = {SwatchWeight \over SwatchArea}$ $TotalWeight = ProjectArea \times YarnDensity$

Formula (extracted text)

$YardsPerGram = {SkeinYardage \over SkeinWeight_{g}}$ $TotalYardage = TotalWeight_{g} \times YardsPerGram$ $TotalSkeins = \lceil {TotalYardage \over SkeinYardage} \rceil$

Formula (extracted text)

$StitchDifference = TargetStitches - CurrentStitches$ $StitchRatio = \lfloor {CurrentStitches \over StitchDifference} \rfloor$
