DAFTAR KONVERSI SATUAN

PANJANG
1 ft = 12 in
1 in = 25,4 mm
1 mile = 5280 ft = 1760 yd = 1,609 km
1 km = 3281 ft = 1093,6 yd = 0,6214
LUAS
1 in2 = 6,452 cm2
1 in2 = 1550 in2 = 10,76 ft2 = 1,196 yd2
o VOLUME
1 ft3 = 7,481 US gallon = 28,32 liter
1 in3 = 16,39 cm3
1 US gallon = 3,785 liter
1 liter = 0,03531 ft3 = 61,02 in3 = 0,2642 US gallon
KECEPATAN
1 ft/s = 30,48 cm/s
1 m/s = 3,281 ft/s = 3,6 km/h
1 mile/h = 1467 ft/s = 1,609 km/h = 0,8684 knot
1 km/h = 0,278 m/s = 0,621 mil/h
o PERCEPATAN
1 ft/s2 = 0,3048 m/s2
MASSA BERAT
1 lb = 0,4536 kg = 7000 grains
1 kg = 2,205 lb
o MASSA JENIS
1 lb/ft3 = 16,02 kg/m3
1 gr/cm3 = 62,43 lb/ft3
GAYA
1 lb = 0,4536 kg (=0,4536 kp) = 4,448 N (newton)
1 kp ( kilopond) = 2,205 lb = 9,807 N (newton)
TEKANAN
1 psi (=1 lb/in2 ) = 0,07031 kg/cm2 = 51,71 mm Hg pada 0 o C
1 kg/cm2 = 14,22 psi = 735,6 mm Hg pada 0 o C = 0,9807 bar
1 atm (standart ) = 14,7 psi = 1,033 kg/cm2 = 760 mm Hg pada 0 o C
1 bar = 105 N/m2 = 105 Pa = 1,0197 kg/cm2 = 14,50 psi

MOMEN PUTAR
1 lb ft = 0,1383 kgm = 1,305 Nm
1 kgm = 7,233 lb ft = 9,807 Nm
ENERGI DAN KERJA
1 ft lb = 0,1383 mkg = 1,356 J = 1/778 BTU
1 mkg = 7,233 ft lb = 9,807 J = 1/427 kcal
1 J = 1 Ws = 107 erg
1 kcal = 427 mkg = 4187 J = 3,969 BTU
1 BTU = 778 ft lb = 1055 J = 0,252 kcal
1 hp hr = 2545 BTU = 0,7475 kWh
1 PS hr = 632,4 kcal = 0,7355 kWh
DAYA
1 W = 1 J/s = 1/1000 kW
Daya kuda metrik : 1 PS = 75 mkg/s = 0,7355 kW = 0,9863 hp
Daya kuda non-metrik : 1 hp = 550 ft lb/s = 0,7475 kW = 1,014 PS
TEMPERATUR
F = 1,8 o C + 32
R = o F + 460 = 1,8 o K
K = o C + 273
KONSTANTA GAS UNIVERSAL
Ř = 1,986 BTU /(mole o R ) = 1545 ft lb / (mole o R )
1,986/cal/(gmole o K) = 848 ( m kg/k mole o K )
LAIN – LAIN
1 cal/gram = 1,8 BTU /lb
1 cal/(gram o K) = 1 BTU / ( lb o R )
1 Btu/lb = 0,56 cal/gram
19040 Btu/lb = 19040 x 0,56 cal/gram= 10662 cal/gram= 10,6621
