Frequently Asked Questions
-
What is an attowatt?
-
An attowatt is a unit of power equal to 10^-18 watts, used to express extremely small rates of energy transfer in scientific and engineering fields.
-
What does calorie (IT)/minute measure?
-
Calorie (IT) per minute measures the rate of heat or energy transfer, representing the transfer of one international-table calorie in one minute.
-
Why convert attowatts to calories per minute?
-
Converting attowatts to calories per minute helps interpret very small power levels in terms of heat energy transfer that is commonly measured in laboratory and physiological applications.
