Convert common shop and engineering units used in CNC programming, inspection, and quoting. Use it when moving between metric drawings, imperial tooling charts, and mixed-unit machines.
Let our engineers find the right factory for your specs. 100% Quality Guaranteed.
Request a Proposal →Unit mistakes are a common source of scrap. Keep original drawing units visible when programming or quoting.
It reduces mistakes when drawings, tools, machines, and supplier charts use different unit systems.
Only round according to the drawing tolerance or shop standard. Extra rounding can create inspection problems.
Length, feed, speed, pressure, torque, power, weight, and temperature conversions are common in machining workflows.
Use this converter when a drawing, tooling catalog, machine control, or inspection report uses a different unit system.
Continue with closely related tools from the machining calculator library.
Use the calculator freely. If the result points to a tooling or process problem, we can source the exact carbide tooling you need from vetted factories in China. Compare factory-direct pricing.
Before you commit to a spec, it helps to know what the market pays for it. These are real, publicly listed factory prices — not a quotation, and not a guess.
We source the tool families below direct from vetted Chinese factories, matched to the material and tolerance you just worked out. Every batch ships with its material certificate and dimensional record.
CONVERTING UNITS FOR AN INQUIRY? Units are the quiet cause of most wrong-goods shipments. See how to write a tool specification that cannot be misread.
We source carbide cutting tools from China for job shops. We do not own a factory, which is why we can quote your drawing against two or three plants that actually run your material.
