Convert between mil, mm, inch, μm and copper weight units.
Decode 4, 5, or 6 band resistor colors to resistance value.
Decode SMD capacitor markings (104, 473) to actual values.
Convert between binary, decimal, hexadecimal and octal.
Convert between copper weight (oz/ft²) and thickness in mil, µm, mm.
A PCB converter is a reference-driven utility that turns one valid technical representation into another valid representation without changing the underlying engineering meaning. Component decoding refers to the process of translating a printed code, color band, or shorthand notation into the actual electrical value used for design, inspection, and purchasing.
These tools are especially useful when a team is switching between imperial and metric dimensions, checking passive component markings, or reviewing legacy drawings that were created with older notation habits. They are not a replacement for component datasheets or fabrication documentation, but they reduce avoidable manual errors in common translation tasks.
| Converter Type | Primary Input | Primary Output | Typical Use Case |
|---|---|---|---|
| Unit Converter | mil, mm, inch, um | Equivalent dimensions | Drawing review and fab communication |
| Resistor Decoder | 4, 5, or 6 color bands | Resistance and tolerance | Assembly inspection and troubleshooting |
| Capacitor Decoder | Numeric SMD markings | Capacitance value | BOM review and part substitution |
| Number Base Converter | Binary, decimal, hex, octal | Equivalent numeric formats | Firmware and register-level debugging |
A PCB converter tool is a utility that translates units, component markings, or numeric formats into a representation that is easier to use during layout, review, sourcing, or manufacturing communication.
PCB design refers to a supply chain where datasheets, CAD defaults, fabrication notes, and manufacturing expectations often mix mil, mm, inch, and micrometer values. Converters reduce mistakes when those conventions meet.
Unit conversion is usually the most frequent task because trace widths, drill sizes, copper thickness, and board outlines can come from different documents with different unit systems.
No. Experienced engineers also use them to double-check assumptions, decode legacy markings, or speed up routine review work during quoting and production release.
Use the converter for speed, then confirm critical numbers against the component datasheet, the fabrication drawing, or a recognized technical reference before release.
For critical conversions, we recommend checking the source document and a neutral reference before design release.
