Comment convertir des litres en gallons ?
Divisez le volume en litres par 3,785 pour obtenir des gallons américains. Un réservoir de 50 litres contient donc 13,2 gallons US, mais seulement 11 gallons impériaux : vérifiez toujours de quel gallon il s'agit.
gallons US = litres × 0,2642litres = gallons US × 3,785
Où ces deux unités servent
Le litre n'appartient pas au système international, qui se contente de le tolérer : il vaut exactement un décimètre cube depuis 1964, après avoir été défini pendant soixante ans par la masse de l'eau, ce qui le rendait plus grand de vingt-huit millionièmes.

1 gallon liquide américain = 3,785411784 litres exactement. Le gallon impérial (Royaume-Uni, Canada) vaut 4,54609 litres, soit 20 % de plus : les deux ne sont pas interchangeables. Méthodologie & sources.
Questions fréquentes
Gallon américain ou gallon impérial ?
Le gallon US vaut 3,785 l, le gallon impérial britannique 4,546 l, soit environ 20 % de plus. Une consommation annoncée en miles par gallon paraît donc meilleure au Royaume-Uni qu'aux États-Unis, à performance identique.
Combien de litres dans un réservoir annoncé en gallons ?
Multipliez par 3,785 pour des gallons américains. Un réservoir de 15 gallons US contient 56,8 litres ; le même chiffre en gallons impériaux donnerait 68,2 litres.
Comment convertir des miles par gallon en litres aux 100 km ?
Divisez 235,2 par la valeur en mpg (US). Ainsi, 30 mpg correspond à 7,8 l/100 km. Pour les mpg impériaux, utilisez 282,5 comme constante.
Le gallon sec américain, c'est encore autre chose ?
Oui. À côté du gallon liquide de 3,785 l, les États-Unis conservent un gallon sec de 4,405 l, soit 268,8025 pouces cubes, réservé aux fruits, aux céréales et aux coquillages. Il dépasse le gallon liquide de 16 % et sert de base au boisseau, qui en vaut huit, soit 35,24 l. Un panier annoncé pour un gallon de myrtilles ne contient donc pas 3,785 l mais 4,4 l.
Combien pèse un gallon d'eau ?
Un litre d'eau pèse 1 kg, donc un gallon américain en pèse 3,79 kg, soit 8,34 livres. Le gallon impérial atteint 4,55 kg, c'est-à-dire 10 livres presque exactement : ce n'est pas un hasard, la loi britannique de 1824 a défini ce gallon comme le volume de dix livres d'eau distillée à 62 °F.
