One microsecond equals 0.001 millisecond. To convert microsecond to millisecond, multiply by 0.001. To go the other way, multiply millisecond by 1000. So 5 microsecond is 0.005 millisecond, 10 is 0.01 and 100 is 0.1. 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.
