Foot (ft). The foot equals exactly 0.3048 meters, or 12 inches, and is widely used for height and room sizes in India, the US and the UK.
Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
There are 3.22174 × 10⁻¹⁷ light years in one foot.
Multiply the number of feet by 3.22174 × 10⁻¹⁷. For example, 10 feet equal 3.22174 × 10⁻¹⁶ light years.
One light year equals 3.10391 × 10¹⁶ feet.
3.22174 × 10⁻¹⁴ light years. Other common values: 100 feet = 3.22174 × 10⁻¹⁵ light years and 10,000 feet = 3.22174 × 10⁻¹³ light years.
