Kinematic Viscosity Converter (m²/s / cSt / ft²/s)

Convert kinematic viscosity (ν = dynamic viscosity / density) between m²/s (square metres per second, SI base), cSt (centistokes, 1 cSt = 1e-6 m²/s = 1 mm²/s), and ft²/s (square feet per second, 1 = 0.09290304 m²/s). Converts via m²/s to the target unit and also lists the equivalent value in all three units for reference. Reference values: water 20°C ≈ 1.004 cSt, SAE 30 oil ≈ 300–400 cSt at 40°C.

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "kinematic-viscosity-converter",
    "arguments": {
  "inputUnit": "cSt",
  "value": 100,
  "outputUnit": "m²/s",
  "decimalPlaces": 6
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
