C2 Conversion factors and Practice
Length
1_Å = 1.0 x 10^-10_m = 1.0 x 10^-8_cm = 1.0 x 10^-1_nm
Area Volume
1” = 2.54_cm 1 in^2 = 6.452_cm^2 1 in^3 = 16.39_cm^3
1_ft = .3048_m 1 ft^2 = .0929_m^2 1 ft^3 = .0283_m^3
1_mi = 1.609_km 1_mi^2 = 2.590_km^2 1_gal = 3.785_l
1_mi = 5280_ft 1_arce = 4840_yd^2 1_gal = 4_qt = 8_pt = 16_cup = 128_ozfl
Mass 2_pt = 1_qt = 32_ozfl
1_lb = 16_oz = .4536_kg 2_cup = 1_pt = 16_ozfl
1_oz = 28.35_g 2_TBSP = 1_ozfl
1_ton = 2000_lb 1_TBSP = 3_tsp
1_amu = 1.6606 x 10^-27_kg 1_ozfl = 29.57_ml
Energy
1000_cal = 1_kcal = 4186.8_J = 3.968_Btu
1_eV = 1.6022 x 10^-19_J
1_MeV = 1.0 x 10^6_eV
Pressure
1_atm = 14.70_psi = 101325_Pa = 760_torr = 760_mmHg = 407.2_inH2O
Power Angle
1_Kwhr = 3.60 x 10^6_J = 860_kcal 1_rev = 360º = 2π_rad
Metric Fun
.000000001_Gm =.000001_Mm =.001_km = .01_hm = .1_dam = 1_m
1_m = 10_dm = 100_cm = 1000_mm = 1.0 x 10^6_µm = 1.0 x 10^9_nm
1_cm^3 = 1_cc = 1_ml = 20_drops of water = 1_g of water
1_mm = 1000_µm & 1_µm = 1000_nm
1_dm^3 = 1_l
Constants Time
π = 3.1416 1_yr = 365.24_day
c = 3.0E10_cm/s
