Volume / Fluids / Capacity



1 liter (1 l) = 10 dl = 100 cl = 1000 ml

Since 1964 is 1 liter (1 l (in the USA often 1 L)) = 1 cubic dm (dm³) and 1 ml = 1 cubic cm (cm³).
Many books state, even today, that 1 ml = 1.000027 cc or 1.000028 cc.
Today 1 ml = 1 cc (1 cubic centimeter)!

1 US quart (qt) = 0.946352946 L

1 Imperial gallon (160 fl oz) = 4.54609 L
1 l = 0.219969248299 Imperial gallon

1 US gallon (128 fl oz) = 3.785411784 L
1 l = 0.264172052358 US gallon

1 US dry gallon = 4.404760 l
1 l = 0.2270271 US dry gallons = 0.9081084 US dry quarts = 1.816217 US dry pints

1 US dry peck (pk) = 8.8097675 L

1 US dry bushel (bu) = 4 peck = 35.23907016688 L

1 US dry barrel (bbl) = 115.6271236 L

1 US liquid barrel (bbl) = 42 US liquid gallons = 158.987294928 L


Weight



1 metric ton = 1000 kg
1 kg = 10 hg = 1000 g
1 g = 1000 mg
1 mg = 1000 µg (mkg)
1 µg = 1000 ng
1 ng = 1000 pg
1 pg = 1000 fg

1 grain = 0.0022857143 ounces (avoirdupois')
1 grain = 0.0020833 ounces (apothecaries' or troy)
1 grain = 0.0647981 g
1 g = 15.432358 grains

1 dram (avoirdupois') = 27.34375 grains = 1/16 ounce (avoirdupois')= 1.7718452 g
1 dram (apothecaries' or troy) = 60 grains = 1/8 ounce (apothecaries') = 3.8879346 g

1 ounce (oz) (avoirdupois') = 16 drams (dr) (avoirdupois weight) = 7.291666 drams (apothecaries' weight) = 28.349523 g
1 ounce (apothecaries' or troy) (oz t) = 8 drams (apothecaries') = 17.554286 drams (avoirdupois') = 31.1034768 g
1 g = 0.035273962 oz (avoirdupois')
1 g = 0.0321507 oz (apothecaries' or troy)

1 pound (1 lb) = 16 ounces = 0.45359237 kg
1 pound (avoirdupois') = 0.45359237 kg = 453.59237 g
1 pound (apothecaries' or troy) = 0.37324172 kg = 373.24172 g
1 kg = 2.2046226 lb (avoirdupois')

1 stone (14 lb) = 0.14 centals = 6.35029318 kg

1 hundredweight (Brit. cwt.) = 1 hundredweights (long) = 112 pounds = 50.802345 kg
1 U.S. centerweight (U.S. cwt.) = 1 hundredweights (short) = 100 pounds = 45.359237 kg

1 long ton = 2240 lb (England) = 1016.0469 kg
1 short ton = 2000 lb (USA) = 907.18474 kg
1 ton (Sweden) = 1000 kg = 1 tonnes (t) = 1 metric tons


Temperature



Centigrade = Celsius = °C = (°F - 32)/1.8
Fahrenheit = °F = (1.8×°C) + 32

0 °C = 32 °F
100 °C = 212 °F
- 40 °C = - 40 °F


Energy



1 calorie = 4.18400 joules (Applies to chemistry and biochemistry) = (Heating 1 g of water 1 degree Celsius (1 Centigrade)).
1 Calorie (1 Cal) = 1000 calories (1000 cal) = 1 kcal
Many authors are quite sloppy and use "calories" and "grams" instead of the more correct terms "kcal" and "g".
Don't follow their steps or the advantage of a stringent use will be lost. The SI system use joule instead of calories. 1 cal (thermochemical) = 4.184 joule (J). 1 g of carbohydrates or protein equals ca. 17 kJ.
If you only consumed 5000 calories ( = 5 kcal) a day you would starve to death in less than two months. A normal consumption is approximately 2500 kcal/day (2 500 000 cal/day).
1 g of glucose = 3.81 kcal
1 g of palmitate (fat) = 9.30 kcal
1 g of alcohol (1.4 ml) = 7 kcal
1 g of protein = ca. 4 kcal (It's actually a lot more and differs between the different amino acids, but the kidneys consume a lot of energy to relieve the body from the resulting urea. The net gain is 4 kcal/g.


Kitchen measures (Mått för matlagning)

1 knivsudd (Sw) = 1 knife's-point
1 tesked (Sw) = 1 teaspoonful = 5 ml
1 matsked (Sw)= 1 tablespoonful = 15 ml
