About this converter
The magnetoelectric voltage coefficient (α) quantifies the electric field generated per unit applied magnetic field in multiferroic and magnetoelectric composite materials. It is measured in V/cm·Oe (CGS system) or equivalently in V·m/A·m (SI), relating volts per unit length to oersteds or amperes per meter of applied field.
Materials scientists, condensed-matter physicists, and magnetoelectric device engineers convert between CGS and SI units when characterising multiferroic ceramics, laminate composites, and thin-film sensors. CGS units (V/cm·Oe) dominate in experimental literature; SI units (V·m/A·m) are required for modelling and for publications in IEEE and IOP journals. Typical values span from a few µV/cm·Oe for single-phase BiFeO₃ to hundreds of V/cm·Oe for optimised PZT/Metglas composites.

How to Convert V/cm·Oe to V·m/A·m
V/cm·Oe to SI (V·m/A·m)
For example, 100 V/cm·Oe × 0.7958 = 79.58 V·m/A·m — a high-performance PZT/Metglas laminate value.
SI to V/cm·Oe
For example, 1 V·m/A·m × 1.2566 = 1.2566 V/cm·Oe.
When You Need to Convert Magnetoelectric Voltage Coefficients
Experimentalists reporting in materials journals (Nature Materials, Physical Review B) typically express α in V/cm·Oe because laboratory lock-in amplifier measurements are set up with applied fields in oersteds and electrode spacings in centimetres. Converting to SI V·m/A·m is required when submitting to IEEE Transactions on Magnetics or when inputting data into COMSOL or ANSYS Maxwell finite-element models.
Sensor designers evaluating commercial magnetoelectric composites for current sensing or biomagnetic detection compare datasheets in different unit systems. A Metglas/PVDF bimorph quoted at 52 V/cm·Oe equals 41.4 V·m/A·m. Magnetic field detection limits and noise floors specified in different unit systems must be converted before directly comparing sensor performance from different suppliers or research groups.
Thin-film researchers growing multiferroic BiFeO₃ or BaTiO₃/CoFeO₄ heterostructures routinely measure coefficients in µV/cm·Oe range (0.1–10 µV/cm·Oe). Converting to V·m/A·m for device modelling and to mV/mm·Oe for cross-group comparisons helps validate whether measured coupling efficiencies are consistent with theoretical predictions based on individual phase properties.
