![]() Always consider your low temperatures too.įactors that affect your actual temperature You can assume a 30 degree difference after rounding, so it’s only going to be 30 degrees max at the top of the mountain (A high of 60 minus your 30 difference)! Remember, that’s for the high. If you’re climbing from 6,000 feet to 14,000 feet, That’s an 8,000 foot difference. Simply subtract this number form your expected low, according to the forecast, and you have the lowest expected temperature, short of some crazy weather event.Įx: The weather man says it’s going to be 60 degrees today for the high in your city. ![]() ![]() I always round up to the nearest 5 just to factor in changes in weather that can’t be planned for, so here I will assume a 20 degree difference. So roughly, you’ll expect to lose at least 17.5 degrees. So, since you’re gaining 5,000 feet in elevation, you’ll use a 5 in your calculation. If you start out at 1000 feet, and climb to 6000 feet, that’s a 5000 foot difference (6000 – 1000 = 5000). Some people use 9.8 degrees Celsius per 1000 meters). You can also use about 1.2 degrees Celsius per ever 1000 feet, or about 1 degree Celsius per 100 meters (source, NFW who showed me my typo on the metric conversion in the comments). You will lose an average 3.5 degrees Fahrenheit for every 1000 feet of elevation you gain. A quick Google with “Mountain (Name) elevation” will normally get you what you need. Reference your topo map, or find these details online. Now you need to know how high up you are going to climb or descend. Here, we’re at 2,000 feet, and our forecast are all for 2,000 feet. If that information isn’t available, it’s usually the same elevation as your official city elevation. Using the National Weather Service website you can a detailed forecast, and they’ll list the elevation of reference on the page. Determine the elevation of reference for the forecast.Īll weather forecasts are referenced to a particular elevation.Look up the local area forecast, and see what the high, and low temperatures are going to be. Again, these are both simplified calculations designed to be done on the fly, they’re not exact. Also, if you do the math using Celcius vs Fahrenheit, you will get slightly different values. They’re not exact, they’re not terribly scientific, and they’re not meant to be used in such a way. Now, before we proceed, these are simple approximations. Here are the steps involved, and a simple equation to reference. Have you ever set off on a warm summer hike to find the temps at the peak in the 50’s or worse?Īvoid these surprises by knowing how to calculate the temperature loss as you climb. If a value you are interested in is not displayed, use the calculator above to convert the temperature, or view the conversion tables page which features temperatures between -460 and 379 Fahrenheit (☏), converted to Celsius (☌).It’s no secret that the temperatures high up in the mountains will be lower than that in the valleys. This table shows a select range of temperatures, converted from Fahrenheit to Celsius (F to C) - from absolute zero to the boiling point of water. ![]() Worked Example Convert 70 Fahrenheit (☏) to Celsius (☌) ☌ = ( 70 - 32 ) / 1.8 = 38 / 1.8 = 21.11 ☌ ∴ therefore, 70 Fahrenheit (☏) is equal to 21.11 Celsius (☌)Ĭheck this result with the conversion calculatorĪlbert Einstein is shown for illustrative purposes.Īnders Celsius (1701–1744), is the proponent of the Celsius temperature scale.
