gigaohm to megaohm
Convert gigaohm (GΩ) to megaohm (MΩ). Use an editable electrical resistance converter, conversion formula, and reference table.
1 GΩ = 1,000 MΩ
Conversion formula
One gigaohm equals 1,000 megaohm. Multiply your value in gigaohm by this factor to get megaohm. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 gigaohm:5 × 1,000 = 5,000 MΩ

About these measurements
Resistance relates voltage to current for a given element.
The base reference used here is the ohm. One gigaohm is 1,000,000,000 base units; one megaohm is 1,000,000 base units.
Important distinctions
Resistance and impedance are not the same physical quantity.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert GΩ to MΩ?
Multiply the quantity in GΩ by 1,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the megaohm to gigaohm converter.
