Going up and down the ladder

Each step is a fixed factor: ×60 from seconds to minutes, ×60 from minutes to hours, ×24 from hours to days. Going the other way, divide. To skip a rung, multiply the factors: 1 hour = 60 × 60 = 3,600 seconds.

Your turn

Convert 7,200 seconds to hours.

Recap
  • 1 min = 60 s; 1 hr = 60 min = 3,600 s; 1 day = 24 hr = 86,400 s.
  • Convert to a smaller unit → multiply. To a larger unit → divide.
  • To skip a step, multiply the conversion factors together.
