Kipimo cha Beaufort (ing. Beaufort scale) ni mfumo wa kupima kasi ya upepo. Msingi wake si kipimo kamili cha mwendo wa upepo bali kutazama matokeo ya upepo katika mazingira. Mfumo huu hutumiwa zaidi duniani ulianzshwa mnamo 1805 na MWingereza Francis Beaufort. Kuna ngazi 12 halafu ngazi ya "sifuri" kama hakuna upepo kabisa. 1 Beaufort 2 Beaufort 3 Beaufort 4 Beaufort 5 Beaufort 6 Beaufort 7 Beaufort 8 Beaufort 9 Beaufort 10 Beaufort 11 Beaufort 12 Beaufort UK Meteorological Office: The Beaufort Scale Archived 9 Aprili 2006 at the Wayback Machine.
