[ Chart using OLD formula ] |
Before you step out into the cold, you might want to check out how cold you will feel. As most people know, when the wind is blowing, a cold temperature can actually seem colder than the thermometer indicates. Below is a chart that will allow you to get prepared for the Artic blast awaiting you outside.
To determine the wind chill, look at the temperature in the left column. Then move across the chart to the right until directly under the speed of the wind shown across the top of the chart. There you will see the perceived temperature waiting for you outside in the winter cold.
For example, if the outside temperature is 10 degrees F and the wind is blowing at 15 miles per hour, the wind chill will require you to bundle up for a perceived temperature of -7 degrees F.
