Jednostki miar i wag

Miary długości:

1 cm = 0.394 in
1 m = 1.094 yard
1 km = 0,621 mile

1 inch (in) (cal) = 2.54 cm
1 foot (ft.) (stopa) = 12 in = 30.4 cm
1 yard(yd.) = 3 ft. = 91.4 cm
1 mila (mile) = 1760 yds = 5280 ft = 1,6 km

Waga:

1 ounce (oz) (uncja) = 28.35 grams
1 pound (lb.) = 16 ozs = 0.454 kilogram
1 quarter (qr.) = 28 lbs = 12.7 kg
1 hundredweight (cwt.) = 4 quarters = 112 lbs = 50.802 kg
1 ton = 20 cwt. = 2240 lbs = 1016 kg
100 pounds = 1 (short) hundredweight = 45.36 kg

Temperatura:

X °Fahrenheita = (X – 32) x 5/9 °C
1 °F = -17,22 °C
X °Celsjusza = X x 9/5 + 32 °Fahrenheita
1 °C = 33,8 °F

Objętość:

1 pinta (pt) = 20 płynnych uncji (fl. ozs) = 0,568 l
1 kwarta (qt) = 2 pts = 40 fl. ozs = 1,136 l
1 galon (gal) = 160 fl.Ozs = 4 qts = 4,546 l

Spalanie paliwa:

X (mil/galon) = 282,49 x 1/X (litrów/100 kilometrów)
