Convert Decades to Anomalistic Months
Convert Decades (dec) to Anomalistic Months (anom.mo) instantly and accurately.
Conversion Formula
anom.mo = dec × 132.5525135
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 Anomalistic Months
The anomalistic month = interval between successive Moon perigees = 27.5546 days = 2,380,713.2 s. Slightly longer than the sidereal month because the Moon's perigee precesses, completing one revolution in ~8.85 years. Governs 'supermoons': a full moon at perigee appears ~14% wider and 30% brighter. Tidal forces at perigee are ~30% stronger than at apogee. 1 anom.mo = 27.5546 d.
