Unit ConversionsCDIP archives its data in metric units. In the website's Recent-Observed section - which displays the latest data from currently active stations - a number of products can be viewed using either English or metric units. On the nowcast swell models and forecast models English units are used, with wave heights measured in feet. Everywhere else on the site, metric units are used. Below is some conversion information that may help in interpreting data.Length conversionsThe primary unit of length used by CDIP is meters(m). To convert from meters to feet, the formula is as follows:(feet) = 3.28 * (meters)
When describing station locations and on maps, distances may given in miles(mi), nautical miles(nm), or kilometers(km). The conversions between these units are as follows: 1 mi = 1.61 km = 0.87 nm Temperature conversionsThe temperature unit used by CDIP is degrees Celsius(C). To convert from Celsius to Farenheit(F), the formula is as follows:(F) = (9/5)*(C) + 32
Other conversionsWind speed is archived in meters per second (m/s).1 m/s = 1.94 knots = 2.24 miles per hour Pressure is archived in millibars (mB). 1 mB = 0.0295 inches of Hg | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
