About Converting Megahenrys to Exahenrys
Megahenry and Exahenry 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: Megahenry is 1000000 henry units, and exahenry is 1000000000000000000 henry units.
Formula
exahenrys = megahenrys × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 megahenry equals 1000000 base units, and 1 exahenry equals 1e+18 base units, so dividing one by the other gives the direct megahenry-to-exahenry factor of 1e-12.
Simple example
1 MH × 1e-12 = 1e-12 EH
1 megahenry = 1e-12 exahenrys.
Real-world example
120 MH × 1e-12 = 1.2e-10 EH
120 megahenrys = 1.2e-10 exahenrys.
Conversion table

Reverse conversion: Exahenry to Megahenry
1e-12 EH × 1e+12 = 1 MH
1e-12 exahenrys = 1 megahenry.
megahenrys = exahenrys × 1e+12

Frequently asked questions
How many exahenrys are in 1 megahenry?
1 megahenry equals 1e-12 exahenrys, using the exact defined conversion factor rather than an estimate.
How do I convert megahenry to exahenry?
Multiply the megahenry value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert exahenry back to megahenry?
Use the reverse factor: 1 exahenry equals 1e+12 megahenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a megahenry?
Megahenry (MH) is a unit of electricity.
What is a exahenry?
Exahenry (EH) is a unit of electricity.
Is the megahenry to exahenry conversion exact?
Yes. Both megahenry and exahenry are defined by fixed standards rather than physical artifacts, so the factor of 1e-12 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.
