Try this example →Barleycorn (bc). The barleycorn is one third of an inch (about 8.47 mm), historically the length of a grain of barley.
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
There are 8,466,700,000,000 fermis in one barleycorn.
Multiply the number of barleycorns by 8,466,700,000,000. For example, 10 barleycorns equal 84,667,000,000,000 fermis.
One fermi equals 1.1811 × 10⁻¹³ barleycorns.
101,600,400,000,000 fermis. Other common values: 5 barleycorns = 42,333,500,000,000 fermis and 100 barleycorns = 846,670,000,000,000 fermis.
