Feet to Decimeters FAQ

  • One foot equals exactly 3.048 decimeters. Since 1 foot = 0.3048 m and 1 m = 10 dm, multiply 0.3048 by 10.

  • Multiply the foot value by 3.048. For example, 10 feet = 30.48 dm (3.048 meters).

  • Almost never. When converting feet to metric, the natural target is meters or centimeters, not decimeters. This conversion exists for mathematical completeness.

Non-Frequently Asked Questions About Feet to Decimeters

Questions nobody should ask - but someone did.

  • A foot is about 3.048 dm. A liter bottle is about 1 dm tall. So yes, a foot is about 3 liter bottles tall. Three bottles of water stacked equals one foot. This is the most refreshing unit conversion available.

  • Shoe sizes use their own bizarre systems: US (inches-based), EU (Paris points of 2/3 cm), UK (barleycorns of 1/3 inch). None use decimeters. A size 10 US men's shoe is about 2.79 dm. '2.79 decimeter shoe' has zero market appeal.

  • A foot is 3.048 dm, so closer to 3.0 than 3.1. For quick estimation, 1 foot is approximately 3 dm with a 1.6% error. For engineering, use 3.048. For cocktail party conversation, '3 decimeters' is close enough and nobody will check.
