We're going to rewrite 0.85 as a fraction. Let's convert a decimal into a fraction.Ĭlick through the slideshow to see how to convert a decimal into a fraction. ![]() The 0 means we're done dividing.Ĭonvert each of these fractions into a decimal. We'll add another 0 after the decimal point and bring it down. Since 2 is greater than 0, we're not finished dividing yet. We'll also add a decimal point after the 0 on top.Ĥ times 2 equals 8. To keep dividing, we'll add a decimal point and a zero after the 1. To convert a fraction to a decimal, we'll just divide the the denominator. To convert a fraction into a decimal, we'll just divide the numerator. Let's see how we can convert 1/4 into a decimal. To refresh your memory on this skill, you can review our Long Division lesson.Ĭlick through the slideshow to learn how to convert a fraction into a decimal. We'll be using a math skill you've already learned: long division. For example, it's easier to subtract 1/6 from 0.52 if you turn 1/6 into a decimal first. You may not do this very often, but converting decimals and fractions can help you in math. Fractions and decimalsĮvery fraction can also be written as a decimal, and vice versa. Learning how to convert fractions, decimals, and percents will also help you as you learn more advanced math. For example, it's much easier to add 1/4 and 0.5 if you turn 0.5 into a fraction. Sometimes it's useful to convert one kind of number into another. Any time we see 1/2, we'll know it can also mean 50% or 0.5. Since they're expressing the same amount, we know that 1/2, 50%, and 0.5 are equal to each other. But we've expressed this amount in three ways: as a fraction, as a percent, and as a decimal. So to convert from ppm to percent, divide the ppm by 10000:Įxample: find how many percent are in 300ppm.Īlso, use P ercent to PPM Calculator for more conversion.In this image, each measuring cup has the same amount of juice in it. The swap will redirect you to Percent to PPM calculator.The reset tab will reset all the values and we can carry out further calculations.Click on the convert tab for the result.Follow these easy steps to get the result. It is a simple online calculator which converts PPM to Percent. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram of soil (mg/kg). Usually describes the concentration of something in water or soil. PPM, or parts-per-million, is a way of expressing very dilute concentrations of substances. ![]() It is often denoted using the percent sign, “%”, or the abbreviations “pct.”, “pct” sometimes the abbreviation “pc” is also used. A percentage is a dimensionless number (pure number). In mathematics, a percentage is a number or ratio expressed as a fraction of 100. This formula is used by people in the agricultural industry for fertilizer calculations, by water treatment professionals, in swimming pool chlorine calculations, and in laboratories by chemists and others. The basic formula for PPM starts with dividing the weight or number of defects by the volume and then multiplying the result by 1,000,000. Parts per million calculations are used for measuring small concentrations in a solution, solid and gas or the number of defects in manufacturing. ![]() Our online PPM to Percent Converter is used to convert ppm (parts-per-million) value into a %.
