About Year (365 days) (yr)
Definition
The common year is a unit of time equal to 365 days, or 31,536,000 seconds.
Mathematical Relationship
1 yr = 365 d = 8,760 h = 525,600 min = 31,536,000 s. A leap year has 366 days (31,622,400 s).
Conversion Formula
To convert years to days: multiply by 365 (or 365.25 for average including leap years). To seconds: multiply by 31,536,000.
Practical Applications
Age calculation, financial year reporting, contract durations, academic years, and historical timeline reference.
Interesting Facts
The year 2000 was a leap year (divisible by 400), but 1900 was not (divisible by 100 but not 400). The Gregorian rule fixes the calendar's drift to 1 day per 3,236 years.
Common Mistakes
Assuming every 4th year is a leap year — century years must be divisible by 400 (so 1900 wasn't a leap year).
Educational Tips
Leap year rule: divisible by 4 = leap, UNLESS divisible by 100, UNLESS also divisible by 400. So 2000 was, 1900 wasn't.
About Hour (h)
Definition
The hour is a unit of time equal to 60 minutes, or 3,600 seconds.
Mathematical Relationship
1 h = 60 min = 3,600 s = 3.6 × 10⁶ ms. There are 24 hours in a day and 8,760 in a non-leap year.
Conversion Formula
To convert hours to minutes: multiply by 60. To convert hours to seconds: multiply by 3,600.
Practical Applications
Work schedules, flight durations, speed limits (km/h, mph), cooking times, and pay rates (hourly wages).
Interesting Facts
Before mechanical clocks, 'hours' varied by season — a summer daytime hour was longer than a winter one. These were called 'temporal hours.'
Common Mistakes
Converting decimal hours to minutes/seconds incorrectly: 2.5 h = 2 h 30 min, not 2 h 50 min. Think base-60.
Educational Tips
The kilowatt-hour (kWh) on your electric bill is energy = power × time. 1 kWh = using 1,000 watts for 1 hour.
