The perception of lower temperatures caused by wind led to the development of many different formulas that attempt to qualitatively predict the effect of wind on this perceived temperature. Measuring the wind isn’t an exact science. I also used the calculator and a double look chart from (I recreated this in my Excel file). I used theweathernetwork to get the temperature, wind mph, and feels like temperature. In columns G and H I converted the values to Celsius using Excel’s handy CONVERT function.ĭownload my Excel file to see the formula in action. Cell E2 is the wind mph (miles per hour). Wind chill “feels like” formula in column F is: This formula is from It’s the standard wind chill formula for the United States & Canada.

Today the “feels like” wind chill figure was colder than Ottawa, Winnipeg, Quebec City, Edmonton and even Yellowknife! Markham Ontario is in the southern part of Canada. Not really cold for me but it’s almost May! It was up to 12C (54 F) about 10 days ago. The wind chill “feels like” temperature was -4C (25F). I had to wear my winter coat and toque! The temperature was 2C (36F) but it was also windy. However, I went for a walk and it’s still cold out! A combination of cold & wind. It’s April 21 and w inter is supposed to be finished here in the Toronto area.
