During a typical chemistry (or science in general) course you will often need to convert one unit into another unit. This is a fundamental skill that all science types need to know. Here are many conversion factors which are often referred to as unit factors. It doesn't hurt a bit to memorize a few of them. But do know, we will always provide a table like this on each an every exam where conversions are necessary.
1 atm = 760 torr
= 760 mm of Hg
= 101325 Pa
= 14.7 psi
1 bar = 100000 Pa
1 bar = .987 atm
1 lb = 453.6 g
1 lb = 0.4536 kg
1 lb = 16 oz
1 kg = 2.205 lbs
1 ton = 2000 lbs
1 tonne = 1000 kg
1 in = 2.54 cm
1 ft = 12 in
1 yd = 3 ft
1 mi = 5280 ft
1 mi = 1.609 km
1 Å = 10-10 m
1 cal = 4.184 J
1 L·atm = 101.325 J
1 eV = 1.602 × 10-19 J
1 C·V = 1 J
1 kWh = 3600 kJ
1 L = 1000 mL
1 L = 1000 cm3
1 L = 0.2642 gal
1 gal = 3.785 L
1 gal = 231 in3
1 gal = 128 fl oz
1 gal = 4 qts
1 gal = 8 pints
1 cup = 8 fl oz
1 cup = 1/2 pint
1 shot = 1.5 oz
1 fl oz = 29.57 mL
1 tbsp ≈ 15 mL
1 tsp ≈ 5 mL
