Hour to Second Conversion Factor
The conversion factor from hours to seconds is defined by the exact relationship that one hour equals 3600 seconds. This factor is based on the standard definitions of these time units.
Definition
The hour (h) and the second (s) are units of time. The hour is a non-SI unit accepted for use with the SI, and the second is the SI base unit of time.
Principle
The conversion is performed by multiplying the value in hours by the exact conversion factor of 3600 to obtain the equivalent value in seconds. The reverse conversion divides by 3600 or multiplies by the inverse factor.
Assumptions
- The conversion uses the exact, defined relationship: 1 hour = 3600 seconds.
- The calculation assumes no rounding is applied to the input value.
Cautions
- The conversion factor is exact, but the result of a calculation may require rounding based on the required precision.
- Always verify that the input value is a time quantity and not subject to other definitions.
