Press the INV button on your calculator (sometimes called 2nd function)Įxample: Let’s assume your climb gains 1,000 feet in altitude (the rise) and the horizontal distance as measured on the map is 1,000 feet (the run). Maths Math Article Percentage Percentage In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. To calculate this, you divide the rise divided by the run, and then obtain the inverse tangent of the result. Multiply 1.4 by 100 to derive percent of slope: 140%Īngle of slope represents the angle that’s formed between the run (remember it’s an idealized flat surface that ignores elevation change) and your climb’s angular deviation from that idealized flat surface. Essentially, divide the fraction value by the total value. Apply the formula by first determining the difference between the two values. You can calculate a percentage on a calculator with a simple formula: (value/total value) × 100. You can follow these steps to calculate the percent increase: 1. Using the percent increase formula often is a simple calculation that involves substituting your numbers into the formula. Multiply 0.166 by 100 to derive percent of slope: 16.6%Įxample: let’s assume your climb gains 700 feet in altitude (the rise) and the horizontal distance as measured on the map is 500 feet (the run). How to calculate the percent increase formula. Multiply 0.5 by 100 to derive percent of slope: 50%Įxample: let’s assume your climb gains 500 feet in altitude (the rise) and the horizontal distance as measured on the map is 3,000 feet (the run). The "run" assumes you're traveling on an idealized flat surface – it does not account for the actual distance traveled once elevation change is factored in.Įxample: let’s assume your climb gains 1,000 feet in altitude (the rise) and the horizontal distance as measured on the map is 2,000 feet (the run). Percent of slope is determined by dividing the amount of elevation change by the amount of horizontal distance covered (sometimes referred to as "the rise divided by the run"), and then multiplying the result by 100.
