This help page is a guide to tropical cyclone wind conversions between knots, miles per hour (mph), and kilometers per hour (km/h), three ways to measure wind intensity. Also, it provides the resulting Accumulated cyclone energy (ACE) from a storm of that intensity. When entering a wind speed into a template, use knots as the number to get the correct wind speed in mph and/or kph. The following table displays all conversions up to 215 mph. To request further conversion/template help, please contact an admin.

Temperature conversions

Celsius to Fahrenheit

Let's say that you want to compare 100 °C to 259 F. However, they are in different units — the easiest way to convert them directly is by using the formula. The freezing point in Celsius, 0 °C, is 32 F, which is added to the simplified variable 1.8C, or in this case, .

As , multiplying it by 1.8 (or 9/5), and then 100, will give you 180. You can then do 180 + 32 to get 212, the final temperature in Fahrenheit. Comparing the two temperatures, you'll see that 259 F is hotter than 100 °C (212 F), or .

Fahrenheit to Celsius

Now, what if you want to convert F to C? That's basically the opposite conversion. Let's compare 100 °C with 256.1 F - for this, we have to use the following formula: .

As , you'll need to subtract 32 from 256.1, giving you 224.1. Dividing it by 1.8 (or 9/5) will give you 124.5, the final temperature in Celsius. Comparing the two temperatures, you'll see that 256.1 F (124.5 °C) is hotter than 100 °C (212 F), or .
