Some Popular Weather Conversions


By By Steve Pool

SEATTLE - As with most of the science field, a lot of weather measurements are conducted on the Metric System. But the U.S. is one of the last countries in the world still on the old Imperial measuring system. So here's some handy conversions to decode some metric weather measurements into something you might be more familiar with:

For wind speeds: 1 knot = 1.15 mph. A knot is also known as a nautical mile-per-hour.

To convert barometric pressure from millibars (metric) to inches of mercury (what's usually seen on air), take the millibar reading and divide by 33.863. So 1015 mb = 29.97 inches of mercury.

And of course, for those that missed our earlier article, to convert Celsius to Fahrenheit, multiply C by 1.8, then add 32.
