About Converting Decaohms to Femtoohms
Decaohm and Femtoohm both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Decaohm is 10 ohm units, and femtoohm is 1e-15 ohm units.
Formula
femtoohms = decaohms × 1e+16
This factor comes from each unit's defined relationship to the category's base unit: 1 decaohm equals 10 base units, and 1 femtoohm equals 1e-15 base units, so dividing one by the other gives the direct decaohm-to-femtoohm factor of 1e+16.
Simple example
1 daOhm × 1e+16 = 1e+16 fOhm
1 decaohm = 1e+16 femtoohms.
Real-world example
120 daOhm × 1e+16 = 1.2e+18 fOhm
120 decaohms = 1.2e+18 femtoohms.

Reverse conversion: Femtoohm to Decaohm
1e+16 fOhm × 1e-16 = 1 daOhm
1e+16 femtoohms = 1 decaohm.
decaohms = femtoohms × 1e-16

Frequently asked questions
How many femtoohms are in 1 decaohm?
1 decaohm equals 1e+16 femtoohms, using the exact defined conversion factor rather than an estimate.
How do I convert decaohm to femtoohm?
Multiply the decaohm value by 1e+16. The converter above does this instantly to whatever precision you set.
How do I convert femtoohm back to decaohm?
Use the reverse factor: 1 femtoohm equals 1e-16 decaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a decaohm?
Decaohm (daOhm) is a unit of electricity.
What is a femtoohm?
Femtoohm (fOhm) is a unit of electricity.
Is the decaohm to femtoohm conversion exact?
Yes. Both decaohm and femtoohm are defined by fixed standards rather than physical artifacts, so the factor of 1e+16 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
