Tips & common mistakes

Quick tips

  • 1 h = 60 min = 3600 s.
  • The official SI symbol is h.
  • 24 h in a day. Use 24-hour time (e.g. 14:30) for unambiguous clarity.

Avoid these

  • Writing "hr" in scientific contexts — the SI symbol is h.
  • Confusing 12-hour AM/PM with 24-hour time — always check.
  • Estimating travel times without rest and connections — real door-to-door is usually 30–50% longer.
