SI / CGS unit converter

For ad-hoc conversions. Published grade pages already carry both unit systems, so no calculation is needed there.

1 mT = 10 Gs · 1 kA/m ≈ 12.566 Oe · 1 MGOe ≈ 7.958 kJ/m³. Click ⇄ to convert in the opposite direction. Grade pages already ship both unit systems from the source sheets, so no manual conversion is needed there.

Glossary

Magnetic material terminology

Term	Definition
Br	Residual induction / remanence — the magnetisation remaining after the external field is removed (mT, Gs, kGs).
Hcb	Coercive force (normal coercivity), measured on the B-H loop (kA/m, Oe).
Hcj	Intrinsic coercivity, resistance to demagnetisation of the magnetisation itself (kA/m, kOe).
(BH)max	Maximum energy product, the figure of merit for permanent magnet strength (kJ/m³, MGOe).
MFR	Melt flow rate — granule flow under a specified temperature and load; a key processing parameter for injection molding.
Anisotropic	Fillers are oriented during forming, giving higher performance in the designed magnetisation direction.
Isotropic	Fillers are unoriented, allowing free pole patterns and multipole magnetisation after molding.

FAQ

Data, revisions and maintenance

Are these values final?

No. They are transcribed from the 2026 sheets supplied by Ruiyi and are marked as reference values on every page. The customer has stated that some parameters may still be adjusted before publication.

Why are component specifications missing?

Ruiyi is finalising the four magnetic-component families. Only categories and process descriptions are published, so no incorrect numbers can reach a buyer.

How is the data maintained?

Each grade is one typed record in data/grades/. Updating a value rebuilds the grade page, the finder, the comparison table and the sitemap — no page-level edits.

Can I get samples?

Yes — send the grade, quantity, application and target properties through the inquiry form and the technical team will respond.

For the site administrator: when Ruiyi confirms revised parameters, update the source arrays in data/grades/ferrite.ts and data/grades/rare-earth.ts, then rebuild. The revision label and TDS filenames should be bumped at the same time.

Need the latest revision?

Request the current specification sheet.

We will send the dated PDF and confirm any parameter changes before you place an order.
