To convert US survey feet to parsecs, multiply the value by 9.87792 × 10⁻¹⁸. To go the other way, multiply parsecs by 1.01236 × 10¹⁷ to get US survey feet.
| US Survey Feet (ftUS) | Parsecs (pc) |
|---|---|
| 1 ftUS | 9.87792 × 10⁻¹⁸ pc |
| 5 ftUS | 4.93896 × 10⁻¹⁷ pc |
| 10 ftUS | 9.87792 × 10⁻¹⁷ pc |
| 25 ftUS | 2.46948 × 10⁻¹⁶ pc |
| 50 ftUS | 4.93896 × 10⁻¹⁶ pc |
| 100 ftUS | 9.87792 × 10⁻¹⁶ pc |
| 250 ftUS | 2.46948 × 10⁻¹⁵ pc |
| 500 ftUS | 4.93896 × 10⁻¹⁵ pc |
| 1,000 ftUS | 9.87792 × 10⁻¹⁵ pc |
| 2,500 ftUS | 2.46948 × 10⁻¹⁴ pc |
| 5,000 ftUS | 4.93896 × 10⁻¹⁴ pc |
| 10,000 ftUS | 9.87792 × 10⁻¹⁴ pc |
| 100,000 ftUS | 9.87792 × 10⁻¹³ pc |
| 1,000,000 ftUS | 9.87792 × 10⁻¹² pc |
25 ftUS × 9.87792 × 10⁻¹⁸ = 2.46948 × 10⁻¹⁶ pc
Try this example →250 ftUS × 9.87792 × 10⁻¹⁸ = 2.46948 × 10⁻¹⁵ pc
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.
Parsec (pc). A parsec is about 3.26 light years and is used by astronomers for distances between stars.
There are 9.87792 × 10⁻¹⁸ parsecs in one US survey foot.
Multiply the number of US survey feet by 9.87792 × 10⁻¹⁸. For example, 10 US survey feet equal 9.87792 × 10⁻¹⁷ parsecs.
One parsec equals 1.01236 × 10¹⁷ US survey feet.
9.87792 × 10⁻¹⁵ parsecs. Other common values: 100 US survey feet = 9.87792 × 10⁻¹⁶ parsecs and 10,000 US survey feet = 9.87792 × 10⁻¹⁴ parsecs.
