Atmospheric Pressure
Conversion: 1 in (inches) = 33.864 mb (millibars) = 33.864 hPa (hecto Pascals)
inches of mercury - abbreviation in. - this unit of pressure is used in the United States
millibar - abbreviation mb - this unit is equal to hPa and is the used as a standard by meteorologists
hecto Pascal - abbreviation hPa - this unit is the metric pressure unit
Wind Speed
Conversion: 1 MPH = 1.61 km/h = 0.87 kts = 0.45 mps
miles per hour - MPH - English measurement
kilometers per hour - km/h - metric measurement
knots - kts - nautical standard
meters per second - mps - scientific standard
Temperature
Convert C to F: multiply C by 1.8 and add 32. 30 C = 30*1.8 + 32 = 86 F
Convert F to C: substract 32 and divide by 1.8. 30F = (30-32) / 1.8 = -1.1 C
Celsius - C - metric unit developed by Celcius (100 is boiling and 0 is freezing)
Fahrenheit - F - English unit developed by Fahrenheit (0 is the coldest temperature of water that can be reached in the liquid phase using a salt additive)
Precipitation
Conversion: 1 in (inch) = 2.54 cm (centimeters) = 25.4 mm (millimeters)
