Conversion Tables

LENGTH
millimeter = mm
meter = m
inch = in.
foot = ft
yard = yd
1 mm = 0.1 cm = 0.04 in.
1 cm = 10 mm = 0.4 in.
1 m = 100 cm = 39.4 in.
1 in. = 2.54 cm
1 ft = 12 in. = 30.48 cm
1 yd = 3 ft = 36 in. = 84.4 cm
 
AREA
square millimeter = sq mm = mm^2
square centimeter = sq cm = cm^2
square meter = sq in. = m^2
square inch = sq in. = 12^2
square foot = sq ft = yd^2
square yard = sq yd = yd^2
1mm^2 = .01 cm^2 = 0.0015 in^2
1 cm^2 = 100 mm^2 = 0.15 in^2
1 m^2 = 104 cm^2 = 1535 in^2
1 in^2 = 6.45 cm^2
1 ft^2 = 144 in^2 = 929 cm^2
1 yd^2 = 9 ft^2 = 8360 cm^2
VOLUME
cubic millimeter = cu mm = mm^3
cubic centimeter = cu cm = cm^3 = cc
cubic meter = cu m = m^3
cubic inch = cu in. = in.^3
cubic foot = cu ft = yd^3
cubic yard = cu yd = yd^3
liter = L
1mm^3 = 10^-3 cc = 0.00006 in.^3
1cc = 10^3 mm^3 = 10^-3 L - 0.06 in.^3
1 m^3 = 10^6 cc = 1000 L = 34.7 ft^3
1 l = 1000 cc = 61 in^3
1 in.^3 = 16.4 cc
1 ft^3 = 1728 in.^3 = 28.4 L
1 yd^3 = 27 ft^3 = 7668 L
