It has been a long time since I looked that those conversions, but IIRC
an imperial gallon is about 4 litres.

A US gallon is slightly less than an imperial gallon, or about 3.84
litres.  I can easily understand the confusion, what with Imperial
Gallons, US Gallons, Litres, etc.,  But in relation to something as
inexact as the size of a koi pond you could just use the factor of 4 to
do the conversions between litres and gallons and it would be close
enough for 99.9% of people. (10 US gallons would actually be
approximately 38.4 litres vs. 40 litres for 10 Imperial gallons, but
that can be considered a tiny difference in an inexact world.)

The US is just as mixed up as we attempt to convert from SAE
measurements to metric.  Miles vs Kilometers, Litres vs Quarts,
Millimeters vs Inches, are just a few of the things we are struggling
with.  We do not have the Imperial measurements in the mix, but we do
have way too much stuff here.
