Methanol (Methyl Alcohol) Unit Converter
Methanol (CH3OH) is a toxic alcohol found in industrial solvents, fuel, and windshield washer fluids. Ingestion is extremely dangerous because methanol is metabolized by alcohol dehydrogenase into highly toxic metabolites.
Clinically, Methanol poisoning is marked by its primary danger: the metabolite Formic Acid, which causes severe Anion Gap Metabolic Acidosis and specific retinal toxicity (potentially leading to permanent blindness). Diagnosis involves measuring the serum concentration and calculating the Osmolal Gap. Treatment is urgent and requires blocking the toxic metabolic pathway (Fomepizole or ethanol). This converter facilitates switching between the SI unit (mmol/L) and the conventional mass unit (mg/dL). [Image of toxic alcohol metabolism pathway]
SI Units
RecommendedMillimoles per liter (Standard International).
Conventional Units
Clinical Context
Toxic Threshold: Blood Methanol levels above 20 mg/dL (6.2 mmol/L) require immediate antidote therapy (Fomepizole/Ethanol).
The diagnosis of Methanol poisoning is often suggested by a high Osmolal Gap and confirmed by the rapid onset of a severe Anion Gap Metabolic Acidosis. The conversion factor relies on MW 32.04 g/mol: 1 mmol/L ≈ 3.204 mg/dL.

Frequently Asked Questions & Tips
Yes. mg/dL (milligrams per deciliter) and mg% (milligrams percent) are numerically identical.
Methanol itself is mildly toxic, but its breakdown into Formic Acid is highly toxic, causing acidosis and blindness, differentiating it from less severe alcohols like ethanol.
