Press Calculate after the entries are in.
What this energy conversion is for
Use this page when a measurement is written in calories and the next step needs watt-seconds. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.
The factor
Multiply by the factor: 1 calorie = 4.184 watt-seconds.
A worked example
10 calories are 41.84 watt-seconds. Multiply the result by the reverse factor if you want the original number back.
How to check it
Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.
The reverse conversion is watt-seconds to calories. A nearby pair in the same units is calories to quads. When the converted number is the input to a job, continue with the calories to eat.
