Formula

Formula
Ω = GΩ × 1e+9

Multiply any value in giga-ohms by 1e+9 to obtain the value in ohms.

Worked example

Convert 1 to Ω.

  1. 01Start with 1 GΩ.
  2. 02Multiply by the conversion factor: 1 × 1e+9 = 1e+9 Ω.
Result1 = 1e+9 Ω

FAQ

What is the conversion factor from GΩ to Ω?
1 GΩ equals 1e+9 Ω. To convert, multiply the value in giga-ohms by 1e+9.
How do I convert 1 GΩ to Ω?
1 GΩ = 1e+9 Ω. For any value, multiply by 1e+9.
How do I convert Ω back to GΩ?
Divide by the same factor — or equivalently, multiply by 1e-9. So 1 Ω = 1e-9 GΩ.
When would I need to convert giga-ohm to ohm?
Resistance conversions between GΩ and Ω are used in electrical-network analysis, instrumentation (RTD/thermistor specification), grounding and bonding measurements, and electronics design. Ohms cover most circuit calculations; kΩ and MΩ appear in input-impedance specs, while milli-ohms cover bus-bar joints and shunt resistors.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
