Measurements

The metric system, put in place on a legal basis in 1795 by the French govt, defines 5 units of measure we use today.

Unit for Area of land: Hectare vs Acres

if you're ever gobbled up with acres, struggling to tranlate sq foot to sq meters, i hear your pain. this is European metric vs American imperial system.

here's a quick recap.
100 sqm = good size 2 bed apartment in Melbourne. this is equiv to 1076 sqfm
1sqm = 10.76 sqft

Now if you're aiming for a piece of land, we're now getting into bigger numbers and different scales of measurement.
1 hectare of land = 10000sqm (think 100m x 100m) which is 107639sq ft
As a comparison, Trafalgar Square in England has an area about 1 hectare.

If you're American, the equiv unit is known as the acre.
1 acre of land = 4046sqm or 44000 sqft, and is approx 40% of a hectare.

Unit of Length (Yard vs Metre)

If you watch golf, you'd have heard of how far these pros can drive the ball in yards.
for example, Woods average drive is 290 yards.

this means 265m.

1 yard = 3 foot = 0.9144 m

Unit of Volume (Litre vs quartz, ounces and gallons)

If you've ordered beer in a bar, this is where you'd be tested.
What's the difference between a pot, pint or scooner?

One of the perplexing aspect of beer drinking is the many receptables that beer come in, and they vary even in Australia states.
A pint is an extremely popular size for drinking beer not of local origin (i.e. Guinness, Kilkenny)
Schooners are an in-between measurement of a pot and a pint, and more favored in NSW than Vic.

Anyway here they are (may differ between states):
1 0z = 28.35 ml
pony = 140ml = 5 oz
Glass or seven = 200ml = 7 oz
pot (285ml) aka middy aka handle = 10 oz
schooner (428ml)
pint (568ml) = 20oz = 2 pots
jug = 1125ml = 40oz = 2 pint


Those getting gas (or what we know as petrol here) means reading gallons instead of litres.
1 liquid Gallon = 3.8 litres

It gets even more confusing to know there is a difference between imperial system and US customary units. The US adopts the latter which is a superset of the Imperial system. for example, their liquid gallon is different to the gallon in Imperial.

the original gallon is 4.5 Litres. even the quartz, pint and ounces differ slightly.

For the cook wannabe, a teaspoon is 5ml and a tablespoon is 15ml. a can of coke is 375ml.

at the very basics also, 1 litre of water has a mass of 1 kg however density of water changes with temperature and slightly with pressure... so be mindful.

Unit of Mass (Grams vs Ounce and Pounds)

1 ounce = 28 grams
1kg = 35.7 ounce
1 kg = 2.2 pounds
