About Decades
A decade = exactly 10 Gregorian years = 315,569,520 s. Climate scientists compute 10-year running means to remove interannual variability; IPCC reports compare decadal temperature anomalies. Moore's Law predicted ~10× transistor density increase per decade. US Census counts are constitutionally mandated each decade. Cultural periods are colloquially labelled by decade (the 1960s, the 1980s). 1 decade = 10 yr.
About Hours
An hour (h) = exactly 3,600 s. The 24-hour day traces to ancient Egypt (10 daylight hours + 2 twilight + 12 night star-rise periods). Time zones are integer or half-hour UTC offsets (exceptions: India +5:30, Nepal +5:45). The kilowatt-hour = 3,600,000 J; Tc-99m half-life = 6.0067 h. Drug dosing and pharmacokinetics are expressed in hours. 1 h = 3,600 s = 60 min = 1/24 day.
