For example, an astronaut would be almost weightless in outer space, but his or her mass would be unchanged from that on Earth. Therefore, one can say that mass is an expression of "how much stuff" something has.
Here is a handy conversion calculator for some common and uncommon mass (weight) terms. Each term is defined in the next section.
|Unit||Equivalent measurements, comments|
|A metric ton is equal to 1,000|
| The prefix "kilo" means 1,000|
|A gram is 1/1000th of a kilogram. A gram is equal to the mass of water contained in a cube one cm on each side (one cubic centimeter = 1 cc = 1 cm3 of water weighs 1 gram).|
|Used primarily for gemstones, one carat = 0.2 gram = 0.00705 ounce. There are 5 carats in a gram.|
|The prefix "milli" means 1/1000. Therefore, 1 milligram = 0.001 grams, or 1000 mg = 1 g. 1 mg = 1e-6 kg. 1 mg = 3.52e-5 ounces.|
|The prefix "micro" means 1/1,000|
|The prefix "nano" means 1/1,000|
|The prefix "pico" means 1/1,000|
|The prefix "femto" means 1/1,000|
|The prefix "atto" means 1/1,000|
|The prefix "zepto" means 1/1,000|
|In the U.S., a long ton = 1.12 short tons = 2,240 pounds = 1.016 metric tons.|
|In the U.S., a ton is 2,000|
|A pound is an English unit of weight. There are 16 ounces or 7,000|
(oz, oz avdp)
|An ounce is equal to 437.5 grains, 1/16 of a pound, or 28.350 grams. The system of having 16 ounces in a pound is called the avoirdupois system. Note:|
(dr, dr avdp)
|Fairly uncommon. There are 256 drams in a pound. 1 dram = 27.34 grains = 1/16 ounces. Caution: apothecary drams and fluid drams are different from the avoirdupois dram (see previous entry).|
|Fairly uncommon. There are 480 grains in a troy ounce and 7,000|
