Length
  • Inch:
  • Foot:
  • Yard:
  • Mile:

1 Foot = 12 Inches

1 Yard = 3 Feet = 36 Inches

1 Mile = 1,760 Yards = 5,280 Feet = 63,360 Inches

1 Foot 0.3048 m = 1⁄3 yd = 12 inches = 0.3048 m

Liquid Volume
  • Fluid Ounces:
  • Cups:
  • Pints:
  • Quarts:
  • Gallons:

16 Cups = 8 Pints = 4 Quart = 1 Gallon
