Gigaohm to Milliohm (GΩ to mΩ)
Convert GΩ to mΩ — Electric Resistance converter
Also written as Gohm to mohm.
One gigaohm equals 1.000000e+12 mΩ, so to convert gigaohms to milliohms you multiply the value by 1.000000e+12. A gigaohm is larger than a milliohm — going the other way, 1 mΩ = 1.000000e-12 GΩ. For example, 10 GΩ = 1.000000e+13 mΩ and 50 GΩ = 5.000000e+13 mΩ.
1 GΩ = 1.000000e+12 mΩ
Gigaohm to Milliohm formula
1 Gigaohm = 1.000000e+12 mΩ
Worked examples
- 25 GΩ = 2.500000e+13 mΩ
- 100 GΩ = 1.000000e+14 mΩ

Resistor notation and where each scale is used
Resistor values are usually written without a decimal point, because decimal points disappear on smudged schematics and photocopies. BS 1852 notation puts the multiplier where the point would go: 4R7 is 4.7 Ω, 4K7 is 4.7 kΩ, and 4M7 is 4.7 MΩ. A value written plainly as "4.7" with no unit is ambiguous and worth checking.
The scale is decimal throughout: 1 MΩ = 1,000 kΩ = 1,000,000 Ω, and 1 Ω = 1,000 mΩ = 1,000,000 µΩ. On this page, 1 GΩ = 1.000000e+12 mΩ.
Milliohms and microohms are the domain of shunts, contact resistance, busbars and battery internal resistance. At these values the resistance of your test leads is no longer negligible, which is why they are measured with a four-wire (Kelvin) connection rather than a standard multimeter.
Megaohms and gigaohms show up in insulation testing and high-impedance input specifications. Readings at this scale are sensitive to humidity and to surface contamination on the board, so they are quoted with test voltage and conditions attached.
