Camels: A good camel should easily be able to travel 100 km in a day.
Cheese: To order the cheese for a wine and cheese party allow 100 g of
cheese per head or 1 kg for every 10 people. There are six 125 mL glasses in
a 750 mL bottle of wine or eight glasses in a litre bottle.
Chemical reactions: You can expect a doubling of the rate of a chemical
reaction with each 10 °C rise in temperature. This also works for biological
reactions, such as yeast, within the enzymešs viability limits.
Cider: Thirty litres of apples will make about ten litres of cider.
Coffee making: Multiply by 100 to work out your coffee needs. A kilogram
of ground coffee can make 100 cups of coffee. These are 200 mL cups so 1 kg
of coffee will make 20 L.
Concrete: It will take a full day for one person to mix and pour two cubic
metres of concrete. If you are inexperienced you may be only able to make
and pour 1 m3.
Cooking fish: Grill fish for 30 seconds for each millimetre of thickness.
A 20 mm fillet should take 5 minutes each side.
Cottage cheese: Ten litres of milk will make a kilogram of cottage cheese.
Cows: Multiply by three to estimate a cowšs water requirements. A cow
needs about three litres of water for every litre of milk she produces.
Cups: I cheat with cups. Although a cup measures 250 mL, I sometimes think
of it as 240 mL. Let me explain; when I use a measuring cup to pour four
cups into a jug, it reaches the one litre mark; so, if I want 2 L I count
out eight cups and if I want 1.5 L of chopped fruit I count out 6 cups. When
I need less than a cup itšs easier for me to think of the cup as 240 mL as
it's easier to divide 240 mL (rather than 250 mL) and the error makes little
difference to my recipes. With this method: 1 cup = 240 mL, 3/4 cup = 180
mL, 2/3 cup = 160 mL, 1/2 cup = 120 mL, 1/3 cup = 80 mL. 1/4 cup = 60 mL.
and 1 tablespoon = 20 mL.
