Essential Knowledge

Common Measurement Units

Length:

mm, cm, m, km • inches, feet, yards, miles

Angles:

degrees (°) • radians (rad) • gradians (gon)

Area:

mm², cm², m², km² • sq in, sq ft, acres

Volume:

mm³, cm³, m³, liters • cu in, cu ft, gallons

Essential Formulas

Circle:

Area = π × r² • Circumference = 2 × π × r

Rectangle:

Area = l × w • Perimeter = 2(l + w)

Triangle:

Area = ½ × b × h • Perimeter = a + b + c

Cylinder:

Volume = π × r² × h • Surface = 2π × r × (r + h)
