In short
One nanosecond equals 1e-6 millisecond. To convert nanosecond to millisecond, multiply by 1e-6. To go the other way, multiply millisecond by 1e+6. So 5 nanosecond is 5e-6 millisecond, 10 is 1e-5 and 100 is 1e-4. Both units measure time, so the conversion is a single exact multiplication with no offset — the same factor works in a spreadsheet or in code.
