# Louisiana Home Lawn Series: Common Conversions

Some home lawn management practices require mathematical calculations. Understanding some basic conversions is helpful if calculations require unit conversions. Units may be in the English, metric or SI (International Standard of Units) systems. Below are common conversions between various measurements across various units.

## Length

1 inch (in) = 25.4 mm (millimeter) = 2.54 cm

1 foot (ft) = 12 in = 30.48 cm = 0.3048 m

1 yard (yd) = 3 ft = 0.914 m

1 mile (mi) = 5,280 ft = 1,760 yd

1 mile (mi) = 1,609.3 m = 1.6093 km

1 millimeter (mm) = 0.03937 in

1 centimeter (cm) = 10 mm = 0.3937 in

1 meter (m) = 100 cm = 1,000 mm = 39.37 in

1 meter (m) = 3.281 ft = 1.094 yd

1 kilometer (km) = 1,000 m = 0.62137 mi

### How to complete a conversion in length:

Convert yards to feet: 10 yards x 3 feet/1 yard = 30 feet

## Area

1 in2 = 6.4516 cm2

1 ft2 = 144 in2 = 929.03 cm2 = 0.0929 m2

1000 ft2 = 92.9 m2

1 yd2 = 9 ft2 = 0.83613 m2

1 acre = 43,560 ft2 = 4,840 yd2 = 0.407 ha

1 cm2 = 100 mm2 = 0.15500 in2

1 m2 = 10,000 cm2 = 10.764 ft2 = 1.1960 yd2

1 hectare (ha) = 10,000 m2 = 0.01 km2

1 hectare (ha) = 2.471 acre

1 km2 = 100,000 m2 = 100 ha = 0.3861 mi2

### How to complete a conversion in area:

Convert yd2 to ft2:10 yd2 x 9 ft2/1 yd2=90 ft2

## Cubic Volume

1 in3 = 16.387 cm3

1 ft3 = 1,728 in3 = 0.028317 m3

1 yd3 = 27 ft3 = 0.76455 mm3

1 cm3 = 1,000 mm3 = 0.0610 in3

1 m3 = 1,000,000 cm3 = 35.03 ft3 = 0.3861 mi2

### How to complete a conversion in volume:

Convert yd2 to ft2:10 yd3 x 27 ft3 /1 yd3=270 ft3

## Mass and Weight

1 ounce (oz) = 28.350 g

1 pound (lb.) = 16 oz = 453.59 g = 0.45359 kg

1 ton = 2,000 lb. = 907.18 kg

1 gram (g) = 1,000 mg = 0.035274 oz

1 kilogram (kg) = 1,000 g = 2.2046 lb.

### How to complete a conversion in weight

Convert pounds to ounces:10 lb. x16 oz/1 lb. = 160 oz

## Liquid Volume

1 fluid ounce (fl oz) = 29.573 milliliters

1 quart (qt) = 2 pints = 32 fl oz = 0.94635 liters

1 gallon (gal) = 4 qt = 128 fl oz = 3.7854 liters

1 milliliter (mL) = 1 cm3 = 0.033814 fl oz

1 liter (L) = 1000 mL = 1.0567 qt = 0.26417 gal

### How to complete a conversion in liquid volume:

Convert gallons to liters:10 gal x 3.785 L/1 gal =37.85 L

## Temperature

oC (Celsius) = (oF - 32) รท 1.8

oF (Fahrenheit) = (oC x 1.8) + 32

### How to complete a conversion in temperature:

Convert Celsius to Fahrenheit:(30oC x 1.8) + 32 = 86 oF
