A direct flight from New York (JFK) to London (Heathrow) takes approximately 7 hours eastbound and 8–9 hours westbound, due to the jet stream. That is 420–540 minutes, or 25,200–32,400 seconds. The Concorde completed the crossing in under 3.5 hours before its retirement in 2003.

Adults generally need 7–9 hours of sleep per night (420–540 minutes). Teenagers need 8–10 hours. Young children need 10–14 hours. Over a lifetime, a person spends roughly 26 years asleep — about 9,490 days or 227,760 hours, assuming 7 hours per night for 80 years.

Approximate cooking times: boiling pasta 8–12 minutes, boiling an egg 6–10 minutes, baking chicken breast 20–30 minutes at 200°C, roasting a whole chicken 1–1.5 hours, baking bread 30–40 minutes. Pressure cookers reduce most cooking times by 50–70%.

A standard lead-acid car battery lasts 3–5 years under normal use. In hot climates, batteries degrade faster and may last only 2–3 years. In very cold climates, they lose charge capacity but may physically last longer. A dead battery from a fully discharged state can take 2–8 hours to recharge with a standard charger.

A calendar year has 365 days × 24 hours = 8,760 hours. A leap year has 8,784 hours. In minutes: 525,600 per year (made famous by the musical "Rent"). In seconds: 31,536,000. The exact tropical year (Earth's orbit) is 365.2422 days = 8,765.8 hours.
