Megaohm to Abohm (MΩ to abΩ)
Convert MΩ to abΩ — Electric Resistance converter
Also written as Mohm to abohm.
One megaohm equals 1.000000e+15 abΩ, so to convert megaohms to abohms you multiply the value by 1.000000e+15. A megaohm is larger than a abohm — going the other way, 1 abΩ = 1.000000e-15 MΩ. For example, 10 MΩ = 1.000000e+16 abΩ and 50 MΩ = 5.000000e+16 abΩ.
1 MΩ = 1.000000e+15 abΩ
Megaohm to Abohm formula
1 Megaohm = 1.000000e+15 abΩ
Worked examples
- 25 MΩ = 2.500000e+16 abΩ
- 100 MΩ = 1.000000e+17 abΩ

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 MΩ = 1.000000e+15 abΩ.
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.
