Feet

Definition

The foot, abbreviated as "ft," is a unit of length used primarily in the imperial and US customary systems of measurement. It equals exactly 12 inches or one-third of a yard. In metric terms, one foot corresponds to approximately 0.3048 meters.

History/Origin

The foot has ancient origins and has been used as a unit of measurement across many civilizations, including the Egyptians, Romans, and Greeks. Its size and definition varied historically, but standardization occurred in the late 16th century in England, leading to its current definition of 12 inches. The term "foot" likely stems from its approximation to the length of an average human foot.

Current Use

Today, the foot is widely used in countries like the United States for measuring height, length, and distances, especially in construction and real estate. In aviation, the foot is a standard unit for altitude worldwide.


Kilometer

Definition

The kilometer, symbolized as "km," is a metric unit of length equivalent to 1,000 meters. It is part of the International System of Units (SI) and is widely used globally for measuring distances, particularly in road travel and geographic mapping.

History/Origin

The kilometer originated from the French Revolutionary metric system in the late 18th century, designed to create a universal, decimal-based measurement standard. It became formally defined as 1,000 meters, derived from the meter's definition based on Earth's meridian arc.

Current Use

The kilometer is the predominant unit for measuring large distances worldwide, especially in countries using the metric system. It is the standard unit for road signs, mapping, and geographical surveys.

Step-by-Step Conversion Instructions

Example 1: Convert 5280 feet to kilometers

  1. Multiply the number of feet by the conversion factor:
    [ 5280 \times 0.0003048 = 1.609344 ]
    Thus, 5,280 feet equals 1.609 kilometers.

Example 2: Convert 150 inches to kilometers

  1. Convert inches to feet:
    [ 150 , \text{inches} \div 12 = 12.5 , \text{feet} ]

  2. Convert feet to kilometers:
    [ 12.5 \times 0.0003048 = 0.00381 ]
    Therefore, 150 inches equals 0.00381 kilometers.


Practical Examples
