Explains how to convert a few meteorological and non-meteorological parameters.

1 kilometer (km) = 1000 meters (m) = 0.6214 statute mile (mi) = 0.5396 nautical mile (n mi) = 3281 feet (ft) 1 mile (mi) = 5280 feet (ft) = 1609 meters (m) = 1.61 kilometers (km) 1 meter (m) = 100 centimeters (cm) = 3.281 feet (ft) = 39.37 inch (in) 1 centimeter (cm) = 10 millimeters (mm) = 0.3937 inch (in) = 0.01 meter (m) 1 micrometer (um) = 10 (to the power of -6) m = 0.0001 cm 1 inches (in) = 2.54 cm = 0.08 ft 1 degree latitude = 111 km = 60 nautical mi = 69 statute mi

1 m/s = 3.60 km/h = 2.24 mi/hr = 1.94 knots 1 knot = 1 n mi/hr = 1.15 mi/hr = 0.51 m/s = 1.85 km/hr 1 mile per hour (mi/hr) = 0.87 knot = 0.45 m/s = 1.61 km/hr 1 kilometer per hour (km/hr) = 0.54 knot = 0.62 mi/hr = 0.28 m/s

1 dyne = 1 gram per centimeter per second per second = 2.2481 X 10 (to the power of -6) pound (lb) 1 newton (N) = 1 kilogram per meter per second per second = 10 (to the power of 5) dynes = 0.2248 lb

1 square centimeter (cm2) = 0.15 in squared 1 square inch (in2) = 6.45 cm squared 1 square meter (m2) = 10.76 ft squared 1 square foot (ft2) = 0.09 m squared

1 meter cubed = 10 (to the power of 6) cm cubed 1 liter (l) = 10 (to the power of -3) m cubed = 1.06 quarts (qt) = 0.264 gallons (gal) = 1000 cm cubed 1 cubic centimeter (cm3) = 0.06 in cubed 1 cubic inch (in3) = 16.39 cm cubed

1 kilogram (kg) = 1000 grams (g) = 2.205 pounds (lb) 1 gram (g) = 0.0353 ounce (oz) = 0.00220 lb 1 metric ton = 1000 kg = 2205 lb

1 millibar (mb) = 100 pascals (Pa) = 100 newtons/meter squared (N/m squared) = 0.0145 lb/in squared = 0.750 mm of mercury (Hg) = 1000 dynes/cm squared 1 standard atmosphere = 1013.2 mb = 101.3 kPa = 14.70 lb/in squared = 760 mm Hg = 29.92 in Hg 1 inch of mercury = 33.865 mb 1 millimeter of mercury = 1.3332 mb 1 pascal = 1N/m(squared)

1 calorie (cal) = 4.186 joules (J) = 4.186 x 10 (to the power of 7) ergs = 1.16 x 10 (to the power of -6) kilowatt-hour (kW h) = 3.97 x 10 (to the power of -3) British thermal units (Btu) = 1 langley-cm squared (ly cm squared)

1 watt (W) = 1 J/s = 14.3353 cal/min = 0.239 cal/s = 0.0569 Btu/min 1 cal/min = 0.06973 1 horse power (hp) = 746 W

To convert degress Fahrenheit to degrees Celsius: Subtract 32 degrees from Fahrenheit, then divide by 1.8 To convert degrees Celsius to degrees Fahrenheit: Multiply Celsius by 1.8, then add 32 degrees To convert degrees Celsius to Kelvins (K): Add 273 to Celsius temperature, as K = Degrees Celsius + 273

1 W/m2 = 0.00143 ly/min = 2.065 ly/day = 0.754 kly/yr = 0.754 kly/yr 1 ly/min = 697.5 W/m(squared)

nano one-billionth = 10 (to the power of -9) = 0.000000001 micro one-millionth = 10 (to the power of -6) = 0.000001 milli one-thousandth = 10 (to the power of -3) = 0.001 centi one-hundredth = 10 (to the power of -2) = 0.01 deci one-tenth = 10 (to the power of -1) = 0.1 hecto one hundred = 10 (to the power of 2) = 100 kilo one thousand = 10 (to the power of 3) = 1000 mega one million = 10 (to the power of 6) = 1,000,000 giga one billion = 10 (to the power of 9) = 1,000,000,000

Mass of the earth = 5.98 X 20 (to the power of 24) kg Mass of the oceans = 1.32 X 10 (to the power of 21) kg Mass of the earth's atmosphere = 5.29 X 10 (to the power of 18) kg Mean radius of the earth = 6371 km Mean distance between earth and the sun = 149.7 X 10 (to the power of 6) km Mean gravitational acceleration at earth's surface = 9.807 m/s(squared) Speed of rotation of a surface point on the earth's equator = 460 m/s Angular velocity of the earth = 7.29 X 10 (to the power of -5) /s
