### WEIGHTS & MEASURES

1 gallon = 4.54 litres and weighs 10lbs. 1 cubic foot holds 6.23 gallons

1 litre = 0.22 gallons and contains 1,000 cubic centimetres (ccs) weighs 1 kilogram

### AQUARIUM and POND CAPACITIES

Length X Width X Depth (in feet) X 6.25 = gallons

Length X Width X Depth (in centimetres) divided by 1000 = litres

Standard aquarium capacities (approx)

18" X 10" X 10" = 6 gallons 24" X 15" X 12" = 15 gallons

36" X 15" X 12" = 20 gallons 48" X 15" X 12" = 30 gallons

Ponds

Length X Width X Depth (in feet) X 6.25 = gallons

Where pond has different levels, divide pond into separate blocks, work out each block's capacity and total them up.

For circular ponds: surface area ( X radius X radius) X depth X 6.25 = gallons

( = 3.142)
