Span (span). A span is 9 inches (0.2286 m), the distance across an outstretched hand.
Parsec (pc). A parsec is about 3.26 light years and is used by astronomers for distances between stars.
There are 7.40842 × 10⁻¹⁸ parsecs in one span.
Multiply the number of spans by 7.40842 × 10⁻¹⁸. For example, 10 spans equal 7.40842 × 10⁻¹⁷ parsecs.
One parsec equals 1.34982 × 10¹⁷ spans.
7.40842 × 10⁻¹⁵ parsecs. Other common values: 100 spans = 7.40842 × 10⁻¹⁶ parsecs and 10,000 spans = 7.40842 × 10⁻¹⁴ parsecs.
