To convert US survey feet to light years, multiply the value by 3.22174 × 10⁻¹⁷. To go the other way, multiply light years by 3.10391 × 10¹⁶ to get US survey feet.
| US Survey Feet (ftUS) | Light Years (ly) |
|---|---|
| 1 ftUS | 3.22174 × 10⁻¹⁷ ly |
| 5 ftUS | 1.61087 × 10⁻¹⁶ ly |
| 10 ftUS | 3.22174 × 10⁻¹⁶ ly |
| 25 ftUS | 8.05436 × 10⁻¹⁶ ly |
| 50 ftUS | 1.61087 × 10⁻¹⁵ ly |
| 100 ftUS | 3.22174 × 10⁻¹⁵ ly |
| 250 ftUS | 8.05436 × 10⁻¹⁵ ly |
| 500 ftUS | 1.61087 × 10⁻¹⁴ ly |
| 1,000 ftUS | 3.22174 × 10⁻¹⁴ ly |
| 2,500 ftUS | 8.05436 × 10⁻¹⁴ ly |
| 5,000 ftUS | 1.61087 × 10⁻¹³ ly |
| 10,000 ftUS | 3.22174 × 10⁻¹³ ly |
| 100,000 ftUS | 3.22174 × 10⁻¹² ly |
| 1,000,000 ftUS | 3.22174 × 10⁻¹¹ ly |
25 ftUS × 3.22174 × 10⁻¹⁷ = 8.05436 × 10⁻¹⁶ ly
Try this example →250 ftUS × 3.22174 × 10⁻¹⁷ = 8.05436 × 10⁻¹⁵ ly
Try this example →US survey foot (ftUS). The US survey foot is about 0.3048006 m, very slightly longer than the international foot, and was used in US land surveys.
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 US survey foot.
Multiply the number of US survey feet by 3.22174 × 10⁻¹⁷. For example, 10 US survey feet equal 3.22174 × 10⁻¹⁶ light years.
One light year equals 3.10391 × 10¹⁶ US survey feet.
3.22174 × 10⁻¹⁴ light years. Other common values: 100 US survey feet = 3.22174 × 10⁻¹⁵ light years and 10,000 US survey feet = 3.22174 × 10⁻¹³ light years.
