• 3

  Converting Decades to Weeks multiplies by 521.775; 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.

• Order-of-magnitude check: 1 Decade = 521.775 Week exactly, so type 1 first — a wildly different weeks figure means a stray comma, wrong field, or flipped direction before you convert real values.

• Direction is the classic slip: Decades → Weeks multiplies by 521.775, never by 0.0019165349. If the weeks answer is off by roughly that factor, the ratio ran backwards — confirm the arrow and re-enter the value.
