KONVENSI FAKTOR

MASSA

1 Kg = 2,21 lb (massa) = 6,02 x 10²⁶ u

1 slug = 32,2 lb (massa) = 14,6 Kg

1 u = 1,66 x 10 ^-27 Kg

PANJANG

1 m = 39,4 inci = 3,28 kaki

1 mi = 1,61 km = 5280 kaki ; 1 inci = 2,54 cm

1 m = 10^-9 meter = 10 Amstrong

1 Amstrong = 10^-10 mater

WAKTU

1 d = 86,4 detik

1 y = 365 d = 3,16 x 10 ⁷ detik

UKURAN ANGULAR

1 rad = 57,3⁰ = 0,159 rev

rad = 180⁰ = ½ rev ; = 3,142

KECEPATAN

1 mi/h = 1,47 kaki/detik = 0,447 m/s

LISTRIK MAGNET

1 C = 3 x 10⁹ statcoul

1 A = 3 x 10⁹ statamp

1 weber/m² = 1 tesla = 10⁴ gauss

GAYA DAN TEKANAN

1 N = 10⁵ dyne = 0,275 lb

1 N/m² = 10 dyne/cm² = 1,45 x 10^-4 lb/inci² =9.87 x 10^-6 atm = 7,6 x 10^-4 cm Hg

ENERGI CAHAYA

1 cal = 4,19 J

1 ev = 1,6 x 10^-19 J = 1,6 x 10^-12 erg

1 tenaga kuda = 746 w = 550 kaki . lb/sec

1J = 10⁷ erg = 0,239 cal = 0,738 ; 1 lb = 2,78 x 10^-7 kwh
