• 2

• Round-trip check: convert your imperial gallons figure to liters, then convert back with the reverse tool — landing on the original number confirms both direction and factor. Skipping this check is how a flipped ratio survives into reports and homework.

• Direction is the classic slip: Imperial Gallons → Liters multiplies by 4.54609, never by 0.21996925. If the liters answer is off by roughly that factor, the ratio ran backwards — confirm the arrow and re-enter the value.
