What it does
Comparing antimicrobial MIC values, toxicology IC50 reports, and animal dosing studies requires repeating molecular-weight arithmetic and tracking counterion salts by hand. Pharmacology Unit Converter converts concentration and dose units across published studies with automated PubChem molecular weight retrieval, salt-form adjustments, batch table processing, and FDA species scaling.
On the Concentration and Dose tabs, enter a value in µg/mL, ng/mL, pM, µM, mg/L, ppm, mg/kg, or mol/kg. Search by compound name, CAS, or PubChem CID for automatic molecular weight lookup, or enter MW manually for synthetic materials. Pick a salt modifier (+HCl, +Na, trihydrate, custom delta) to compute effective MW before molar conversion. Results update live across the full unit palette with effective MW and step-by-step arithmetic shown for lab notebooks.
The Batch tab processes tables up to 50 compounds simultaneously from pasted text or uploaded CSV files. The Species and Route tab scales reported animal doses (such as mouse LD50 or rat ED50 values) to Human Equivalent Doses (HED) using FDA 2005 HED Km factors, custom body weights, and route bioavailability (oral, IP, IV, SC) adjustments.
Why researchers use it
- Eliminate manual mass-to-molar conversion math errors across compound screening panels
- Fetch parent molecular weights automatically from PubChem by name, CAS, or CID
- Apply salt-form counterion corrections before calculating final molarity or dose values
- Batch-process multi-compound literature tables up to 50 rows in one click
- Scale animal doses to human-equivalent doses using official FDA 2005 Km standards
- Export formatted TSV, Markdown tables, or CSV files directly into Excel and GraphPad Prism
Best for
- Comparing antimicrobial MIC or cell assay IC50 values reported in µg/mL versus µM
- Converting drug doses between mass-based (mg/kg) and molar-based (µmol/kg) units
- Calculating Human Equivalent Dose (HED) starting doses for clinical protocol design from mouse or rat studies
- Standardizing multi-compound screening datasets extracted from published patents or journals
- Documenting salt-corrected molecular weights and formula traces in lab notebooks
When to use this vs alternatives
Choose Pharmacology Unit Converter when translating published concentration values, adjusting for counterion salt forms, or performing animal-to-human dose scaling. Use Bio-Unit Converter for general lab solution preparation and C1V1 volumetric dilution recipes. For powder-to-solution mass recipes or non-linear dose-response curve fitting, see our dedicated stock preparation and curve fitting tools.
What makes it different
Traditional vendor molarity tools and generic web converters require manual molecular weight lookup and fail to account for salt counterions, batch table processing, or species scaling guidance.
Pharmacology Unit Converter unifies concentration conversion, dose conversion, PubChem MW lookup with salt adjustment, 50-row batch CSV processing, and FDA HED species/route scaling in one tabbed workspace with formula traces and citation-ready exports—free in the browser with no account.
How to get started
- Select Concentration or Dose mode, then search for your compound by name, CAS, or PubChem CID (or enter a manual molecular weight).
- Choose a Salt Form modifier (+HCl, +Na, trihydrate, etc.) if working with a salt or hydrated compound to compute effective molecular weight.
- Enter your value and select its unit (such as µg/mL or mg/kg) to view instant conversions across all target units.
- Open Species / Route mode to scale doses between animals and humans by choosing source/target species and administration routes.
- Use Batch Table mode to drag and drop a CSV or paste a table with Compound, Value, and Unit columns to process up to 50 rows simultaneously.
- Click Copy TSV or Copy Table to export formatted results directly into GraphPad Prism, Microsoft Excel, or your lab notebook.
