About Hour and Second

Detailed information about both units of measurement.

METRIC UNIT

Hour

h
Definition
A unit of time equal to 60 minutes or 3,600 seconds. The standard unit for daily timekeeping.
SI / Standard Information
SI-accepted unit. Divided into 60 minutes, each containing 60 seconds. The 24-hour day dates back to ancient Egyptian astronomy.
Approximate Comparison
An hour is roughly the length of a TV show or a lunch break extended.
Practical Applications
  • Work and shift scheduling
  • Travel and journey planning
  • Energy consumption billing (kWh)
  • TV and media runtime
Real-World Examples
  • A standard workday is 8 hours
  • A flight from New York to London takes about 7 hours
  • The human sleep cycle is about 6-9 hours
METRIC UNIT

Second

s
Definition
The SI base unit of time. Defined by the radiation frequency of the cesium-133 atom.
SI / Standard Information
SI base unit (s). Defined as 9,192,631,770 periods of radiation from cesium-133. The most precisely measured SI unit.
Approximate Comparison
One second is roughly the duration of a single heartbeat or a quick snap of the fingers.
Practical Applications
