Span (span). A span is 9 inches (0.2286 m), the distance across an outstretched hand.
Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
There are 2.4163 × 10⁻¹⁷ light years in one span.
Multiply the number of spans by 2.4163 × 10⁻¹⁷. For example, 10 spans equal 2.4163 × 10⁻¹⁶ light years.
One light year equals 4.13855 × 10¹⁶ spans.
2.4163 × 10⁻¹⁴ light years. Other common values: 100 spans = 2.4163 × 10⁻¹⁵ light years and 10,000 spans = 2.4163 × 10⁻¹³ light years.
