• 1

  This page converts Square Miles to Feddans using the exact reference factor 616.542. That is the standard figure, so the results here match reference tables rather than rounded approximations.

• 2

  Converting Square Miles to Feddans multiplies by 616.542; the reverse direction divides by the same figure, so confirm the direction label before copying the result — near-one factors hide a swapped direction from a casual glance.

• 3

  Enter plain decimal numbers without thousand separators: a comma can be read as a decimal mark in some locales and silently change the magnitude of the Square Miles value you meant to convert to Feddans.

• Order-of-magnitude check: 1 Square Mile = 616.542 Feddan exactly, so type 1 first — a wildly different feddans figure means a stray comma, wrong field, or flipped direction before you convert real values.

• Direction is the classic slip: Square Miles → Feddans multiplies by 616.542, never by 0.0016219495. If the feddans answer is off by roughly that factor, the ratio ran backwards — confirm the arrow and re-enter the value.
