Salicylate Unit Converter
Salicylate (Salicylic Acid) is the active metabolite of Aspirin (Acetylsalicylic acid). It is widely used as an analgesic, antipyretic, and anti-inflammatory agent.
Monitoring salicylate levels is critical in cases of suspected **Salicylate Toxicity (Salicylism)**, which can cause respiratory alkalosis, metabolic acidosis, and neurotoxicity. This converter facilitates switching between the standard mass units (mg/dL) and SI molar units (mmol/L).

Clinical Context
Interpretation:
• Therapeutic Range: 15 – 30 mg/dL (1.1 – 2.2 mmol/L).
• Toxicity (Early): > 30 mg/dL (> 2.2 mmol/L).
• Severe Toxicity: > 80 – 100 mg/dL (> 5.8 – 7.2 mmol/L) often requires dialysis.
Conversion Logic:
Molecular Weight of Salicylic Acid: ~138.12 g/mol.
1 mg/dL ≈ 0.0724 mmol/L.
1 mmol/L ≈ 13.81 mg/dL.

Frequently Asked Questions
Yes. This test measures salicylate, the active metabolite of aspirin. It is also used for other salicylate-containing drugs (e.g., Pepto-Bismol).
It is the most common unit in US emergency medicine for toxicology, while mmol/L is standard in Europe and Canada.
