When you need to convert ohms to megaohms

Comparing specifications written for a different market.
Checking a figure quoted in an unfamiliar unit before acting on it.
Converting values consistently across a spreadsheet, report or shopping list.

Common mistakes to avoid

Dividing when you should multiply. Because 1 ohm = 0.000001 megaohms, the answer should be smaller than the number you started with.
Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

Ohm (Ω): The SI unit of electrical resistance. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
Megaohm (MΩ): One million ohms. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
