Mass Conversions

Mass is the amount of material contained within a defined volume. Technically, it is a measure of a body's resistance to acceleration, but most people don't think of it that way.

This table provides some of the most often used conversion factors between units.

Standard units = Kilogram (kg)

	ounce	pound	ton	gram	kilogram	slug	u^†
1 oz =	1	6.250 * 10^-2	3.125 * 10^-5	28.35	2.835 * 10^-2	1.942 * 10^-3	1.708 * 10²⁵
1 lb =	16	1	0.0005	453.6	0.4536	3.108 * 10^-2	2.732 * 10²⁶
1 ton =	3.200 * 10⁴	2000	1	9.072x10⁵	907.2	62.16	5.465 * 10²⁹
1 g =	3.527 * 10^-2	2.205 * 10^-3	1.102 * 10^-6	1	0.001	6.852 * 10^-5	6.024 * 10²³
1 kg =	35.27	2.205	1.102 * 10^-3	1000	1	6.852 * 10^-2	6.024 * 10²⁶
1 slug =	514.8	32.17	1.609 * 10^-2	1.459 * 10⁴	14.59	1	8.789 * 10²⁷
1 u =	5.855 * 10^-26	3.660 * 10^-27	1.829 * 10^-30	1.660 * 10^-24	1.660 * 10^-27	1.137 * 10^-28	1

† = atomic mass unit




About RF Cafe

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
