This tool applies the exact conversion formulas: °F = °C × 9/5 + 32, K = °C + 273.15, °R = K × 9/5. We warn if you go below absolute zero, since that's physically impossible. The table at the bottom shows your value on all four scales at once. Runs entirely in your browser.","category":"calc","categoryName":"Calculators","keywords":["celsius to fahrenheit","fahrenheit to celsius","c to f","f to c","kelvin converter","celsius to kelvin","rankine converter","temperature converter","temp converter","convert temperature","degrees converter","absolute zero","k to c","f to k"],"badge":"Converter","url":"https://toolsly.tools/temperature-converter","inputs":[{"type":"number","key":"value","label":"Value","defaultValue":100,"step":0.01},{"type":"select","key":"from","label":"From","defaultValue":"C","choices":[{"value":"C","label":"°C (Celsius)"},{"value":"F","label":"°F (Fahrenheit)"},{"value":"K","label":"K (Kelvin)"},{"value":"R","label":"°R (Rankine)"}]},{"type":"select","key":"to","label":"To","defaultValue":"F","choices":[{"value":"C","label":"°C (Celsius)"},{"value":"F","label":"°F (Fahrenheit)"},{"value":"K","label":"K (Kelvin)"},{"value":"R","label":"°R (Rankine)"}]}],"outputs":[{"key":"converted","label":"Converted value"},{"key":"kelvin","label":"In Kelvin"},{"key":"table","label":"All scales","multiline":true},{"key":"notes","label":"Notes","multiline":true}],"invocation":{"webUi":"https://toolsly.tools/temperature-converter","api":null,"notes":"Currently invoked via the web UI at `webUi`.
