  Unit Conversion

Length
1 in = 2.54 cm = 0.0254 m
1 ft = 30.48 cm = 0.3048 m
1 yard = 91.44 cm = 0.9144 m
1 mile = 1.6093 Km = 1609.3 m

Use engineering units. For example: 5.23e-7
From:
To:

Area
1 in2 = 6.4516 cm2
1 ft2 = 0.0929 m2
1 acre = 0.4047 hectares = 4047 m2

Use engineering units. For example: 5.23e-7
From:
To:

Volume
1 in3 = 16.387 cm3
1 ft3 = 0.0283 m3
1 us f.oz = 29.574 ml
1 imp f.oz = 28.41 ml
1 us gal = 3.7854 l
1 imp gal = 4.546 l

Use engineering units. For example: 5.23e-7
From:
To:

Weight
1 OZ = 28.35 g
1 lb = 0.4536 kg = 453.6 g
1 imp ton = 1016 kg

Use engineering units. For example: 5.23e-7
From:
To:

Temperature
oF = oC*1.8 + 32
oC = (oF - 32) / 1.8
oR = oF + 459.67
K = oC + 273.15
