Gallons to litres
Metric/Imperial Measures (Capacity).
To convert between gallons and litres we can use
the fact that 1 gallon ? 4½ litres. This is a
good approximation with an error of only about 1.

Metric/Imperial Measures (Capacity).
To convert between gallons and litres we can use
the fact that 1 gallon ? 4½ litres. This is a
good approximation with an error of only about 1
When we converted gallons to litres we multiplied
by 4½, when we convert from litres back to
gallons we simply do the opposite and divide by
4½.

Litres to pints
Metric/Imperial Measures (Capacity).
Since 4½ litres ? 1 gallon 8 pints then
4½ litres ? 8 pints
So 1 litre ? 8/4½ pints ? 1¾ pints.
This is a good approximation and has an error of
less than 1.
1 litre ? 1¾ pints
21
Metric/Imperial Measures (Capacity).
To make very rough, rapid mental calculations
between litres and pints you could use the much
less accurate approximation of 1 litre ? 2 pints
although this gives an answer that is about 14
too big.
