4 Best Free Online Rain to Snow Calculator Websites

Here is a list of the best free online Rain to Snow Calculator websites.  Snowfall is typically calculated by measuring the depth of accumulated snow using a ruler or snow gauge. Snowfall can be estimated using snow-to-liquid ratio guidelines. This provides a rough conversion between rain and snow. A rain to snow calculator is a tool that estimates the equivalent amount of snowfall for a given amount of liquid precipitation (rain). It typically takes into account factors like temperature and humidity to provide an approximate conversion.

This post covers 5 online calculators where you can calculate rain to snow. These calculators provide you with a rough estimation of snowfall based on the rainfall data. To perform the calculation, you have to provide the rainfall. Rainfall can be in millimeters, meters, inches, or feet. Along with that, you have provided the outside temperature. Then the calculators use the rain-to-snow ratio to estimate the appropriate snowfall.

OmniCalculator.com is a free website where you can find hundreds of online calculators. The websites covering a wide range of topics and scenarios offer free calculators that are easy to use. You can use OmniCalculator’s Rain to Snow Calculator to calculate the expected rain to snow ratio based on the temperature outside. The calculator needs you to select the outside temperature along with the rain in inches, millimeters, meters, or feet. For the temperature, the calculator has 8 temperature range options from -3 degrees Celsius to over 29 degrees Celsius. Based on your conditions, you can add your values to the calculator and perform the calculation to get the expected snowfall. This calculator also has an advanced option that lets you factor in the snow coefficient into the calculation. A snow coefficient typically represents the ratio or factor used to estimate how much liquid precipitation (rain) will translate into a certain amount of snowfall. It accounts for variables such as temperature, humidity, and snowflake size. Thus, if you are aware of the snow coefficient, you can toggle the advanced option to include that in the calculation and get more accurate calculations.

Frequently Asked Questions

It is a simple tool to estimate the equivalent amount of liquid precipitation (rain) for a given snowfall amount, considering factors like temperature and humidity.

The equivalent snowfall for 10 inches of rain depends on various factors, but a common estimate is a 10:1 snow-to-liquid ratio, suggesting 10 inches of rain roughly equals 100 inches of snow under certain conditions.

One centimeter (1 cm) of snow is approximately equivalent to 0.4 inches of snow.

One inch of snow generally contains about 0.1 inches (0.254 centimeters) of water equivalent when melted.

Snowfall is typically calculated by measuring the depth of accumulated snow using a ruler or snow gauge, and its water content can be estimated through methods like weighing the snow or using a snow-to-liquid ratio, which relates snow depth to the equivalent liquid precipitation.

On average, snow contains about 10% water content.

Snow is frozen water and typically forms at temperatures below freezing, usually at or below 32 degrees Fahrenheit (0 degrees Celsius).

Yes, all snow is made up of fresh water in its frozen form.
