FACTORES DE CONVERSIÓN ÚTILES

LONGITUD

1 m = 100 cm = 3,28 pies  =

1 km = 1000m

1 pulg = 2,54 cm

1 pie = 12 pulg = 30,48 cm

1 yd = 1 yarda = 3 pies = 36 pulg

1 Å = 10^-8 cm

1milla = 3,086x10¹⁶ m

1 a.l.= 1 año luz = 9,46x1015 m

1 pc = 1 parsec = 3,086x10¹⁶ m

MASA

1 Kg = 1000 g = 2,2 lb

1 lb = 453,6 g = 16 onz

1 TM = 10³ kg = 2200 lb

1 TL = 2240 lb

1 TC = 2000 lb

1 qq = 100 lb

1 slug = 14,59 kg

VOLUMEN

1 l = 1 dm³= 1000 cc

                          1 cc = 1cm³ = 1ml

1 m³ = 1000 l

1 pie³ = 28,32 l

1 galón Americano = 3,785 l

1 Galón Ingles = 4,546 l

1 pinta = 0,473 l

FUERZA

1N = 1 Newton = 10⁵ dinas

1 Kg_f = 9,8 N = 2,205 lb_f

1 lb_f = 453,6 gr_f = 32,17 pdl

1 pdl = 0,1383 N

ENERGIA

1 J = 1 Joule = 10⁷ erg

1 BTU = 252 cal = 778 lb_f-pie

1 cal = 4,186 J

1 Kw-h = 860 Kcal = 3,6x10⁶ J

1 lb_f-pie = 1,356 J

POTENCIA

1 Hp = 746 W = 550 lbf-pie/s

1 Kw = 1000 W = 1,34 Hp

1 W = 1 J/s

1 BTU/h = 0,293 W

1 cal/s = 3,087 lb_fpie/s

TEMPERATURA

˚C = ˚K – 273 =(5/9)(˚F – 32 )=(5/9)(˚R – 492)

˚F = (9/5)(˚K – 460) = (9/5)(˚C + 32) = ˚R – 460
