DNA Copy Number Calculator (Concentration → Copies)
Convert DNA mass concentration to copies/µL via copies = c(g/µL) × Avogadro ÷ (bp × 660), with ng/µL–pg/µL–µg/µL units, pmol/µL output, total copies per volume, and A260-overestimation caveats. Lab-planning use only.

Quick start
Call this tool from your code in three languages.
cURL
curl -X POST 'https://api.elysiatools.com/en/api/tools/dna-copy-number-calculator' \
-H 'Content-Type: application/json' \
-d '{"concentration":50,"concentrationUnit":"ng/µL","templateLengthBp":5000,"volumeUl":2,"decimalPlaces":2}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.

| Name | Type | Required | Description |
|---|---|---|---|
| concentration | number | Yes | Measured DNA concentration in the selected unit. |
| concentrationUnit | select | Yes | ng/µL and µg/mL are numerically identical; pg/µL is the Qubit range. |
| templateLengthBp | number | Yes | Total double-stranded length in bp: plasmid size, genome size, or amplicon length. |
| volumeUl | number | No | Volume of template added (e.g. per PCR reaction); enter 0 to skip the total-copies calculation. |
| decimalPlaces |
MCP integration
Add this tool to your Model Context Protocol server so AI agents can list and call it.

}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": "dna-copy-number-calculator",
"arguments": {
"concentration": 50,
"concentrationUnit": "ng/µL",
"templateLengthBp": 5000,
"volumeUl": 2,
"decimalPlaces": 2
}
}
}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).
