Precision and interpretation
Examples are rounded for display. Keep the unrounded factor for intermediate calculations and round the final answer to match the precision of the original measurement. Extra decimal places do not make a measured quantity more accurate.
Area factors are squared length factors. Using a linear factor can produce a substantial error in a floor plan or land calculation.
Common questions
How do I reverse this conversion?
Divide the target-unit value by the forward factor, or use the inverse converter. Multiplying by the same factor again is not the inverse operation.
Why can the displayed answer differ slightly?
Display rounding and numerical precision can produce a small difference from an exact fractional calculation. For technical work, retain sufficient precision and confirm the unit convention required by the source.
