The calculator may round displayed results.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to use the calculator<\/h2>\n<ol>\n<li>Enter a number in the <strong>Temperature in Celsius<\/strong> field. The default is 25 \u00b0C; you can replace it with a positive, zero, negative, or decimal value.<\/li>\n<li>Read the results labeled <strong>Fahrenheit<\/strong>, <strong>Kelvin<\/strong>, <strong>Rankine<\/strong>, <strong>Newton<\/strong>, <strong>Delisle<\/strong>, <strong>Reaumur<\/strong>, and <strong>R\u00f8mer<\/strong>. All seven results refer to the same temperature you entered.<\/li>\n<li>Check the unit beside each result before copying it. For example, kelvin uses K without a degree sign, while Rankine uses \u00b0R.<\/li>\n<\/ol>\n<h2>What Celsius conversion results mean<\/h2>\n<p>A temperature scale assigns a number to a thermal state. The scales in this calculator use different zero points, different-sized degrees, or both. Conversion changes the number and unit, not the temperature itself. For example, 25 \u00b0C, 77 \u00b0F, and 298.15 K describe the same temperature.<\/p>\n<p>Fahrenheit is commonly used for weather and everyday temperatures in the United States. Kelvin is the thermodynamic temperature scale used widely in science: a change of 1 \u00b0C has the same size as a change of 1 K, but 0 K corresponds to \u2212273.15 \u00b0C. Rankine also starts at absolute zero, but its degree has the same size as a Fahrenheit degree. If you need to start with another unit, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/fahrenheit\/\">Fahrenheit converter<\/a> or <a href=\"https:\/\/wpcalc.com\/en\/converters\/kelvin\/\">Kelvin converter<\/a>.<\/p>\n<p>Newton, Delisle, R\u00e9aumur, and R\u00f8mer are historical scales. Their numbers can look unfamiliar even for ordinary temperatures. Delisle runs in the opposite direction from Celsius: as Celsius rises, the Delisle reading falls. R\u00f8mer starts at 7.5 \u00b0R\u00f8 when Celsius is 0 \u00b0C. Keep the scale name and unit with any result so it is not mistaken for a reading on another scale.<\/p>\n<h2>Reference points and practical limits<\/h2>\n<p>Two useful checks are the freezing and boiling points of water at standard atmospheric pressure. The table shows their conventional scale values; an actual boiling point changes with pressure.<\/p>\n<table>\n<thead>\n<tr>\n<th>Reference point<\/th>\n<th>Celsius<\/th>\n<th>Fahrenheit<\/th>\n<th>Kelvin<\/th>\n<th>Delisle<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Water freezes<\/td>\n<td>0 \u00b0C<\/td>\n<td>32 \u00b0F<\/td>\n<td>273.15 K<\/td>\n<td>150 \u00b0De<\/td>\n<\/tr>\n<tr>\n<td>Water boils<\/td>\n<td>100 \u00b0C<\/td>\n<td>212 \u00b0F<\/td>\n<td>373.15 K<\/td>\n<td>0 \u00b0De<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Enter an absolute temperature, not a temperature change. For instance, a rise of 10 \u00b0C is a rise of 18 \u00b0F, but converting the temperature 10 \u00b0C gives 50 \u00b0F because the Fahrenheit formula also adds 32. Kelvin likewise adds 273.15 when converting a temperature, not when converting a difference.<\/p>\n<p>The calculator applies its equations to the number entered, even below \u2212273.15 \u00b0C. Such an entry produces negative kelvin and Rankine values, which do not represent physically possible thermodynamic temperatures. Results may also be rounded for display, so retain appropriate precision if you use a conversion in further calculations.<\/p>\n<p>If your starting value is in Rankine rather than Celsius, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/rankine\/\">Rankine converter<\/a> to convert in the other direction.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Enter a temperature in Celsius to convert it to Fahrenheit, Kelvin, Rankine, Newton, Delisle, R\u00e9aumur, and R\u00f8mer.<\/p>\n","protected":false},"author":70,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[3],"tags":[17],"class_list":["post-55832","post","type-post","status-publish","format-standard","hentry","category-converters","tag-chemistry-units"],"acf":[],"_links":{"self":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/55832","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/users\/70"}],"replies":[{"embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/comments?post=55832"}],"version-history":[{"count":3,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/55832\/revisions"}],"predecessor-version":[{"id":65254,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/posts\/55832\/revisions\/65254"}],"wp:attachment":[{"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/media?parent=55832"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/categories?post=55832"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wpcalc.com\/en\/wp-json\/wp\/v2\/tags?post=55832"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
