Span (span). A span is 9 inches (0.2286 m), the distance across an outstretched hand.
Nanometer (nm). A nanometer is one billionth of a meter, used for wavelengths of light and the size of molecules.
There are 228,600,000 nanometers in one span.
Multiply the number of spans by 228,600,000. For example, 10 spans equal 2,286,000,000 nanometers.
One nanometer equals 4.37445 × 10⁻⁹ spans.
2,743,200,000 nanometers. Other common values: 5 spans = 1,143,000,000 nanometers and 100 spans = 22,860,000,000 nanometers.
