About Medical Unit Converter
Medical measurements use specific units that vary by country. Blood pressure: mmHg worldwide. Blood glucose: mg/dL (US), mmol/L (UK/EU, most countries). Cholesterol: mg/dL (US), mmol/L (rest). Weight: kg (most countries), lbs (US), stones (UK informal). Furthermore, converting between these systems is essential for patients using international health information.
What is a Medical Unit Converter?
Blood glucose: 1 mmol/L = 18 mg/dL. Cholesterol: 1 mmol/L = 38.67 mg/dL. Blood pressure: 1 mmHg = 0.133 kPa. Normal blood glucose (fasting): 4-7 mmol/L = 72-126 mg/dL. Furthermore, blood pressure: normal <120/80 mmHg = <16/10.7 kPa.
The Medical Unit Converter is a free browser-based tool available on LazyTools. Furthermore, it requires no installation and works on any device with a modern browser.
Why use this tool
This tool saves time on repetitive medical unit converter tasks. Furthermore, browser-based processing keeps your data private.
Moreover, consistent results eliminate manual calculation errors and improve workflow efficiency.
Common mistakes
Always verify the output for critical applications. Furthermore, browser-based tools rely on JavaScript — results may vary slightly between browsers.
Copy the output before closing the tab, as browser tools do not save state between sessions. Moreover, bookmark the tool for easy access.

For best results, use a modern browser (Chrome, Firefox, Edge). Moreover, if a tool does not load correctly, try refreshing the page.
Frequently asked questions
Divide by 18. 180 mg/dL = 10 mmol/L. Furthermore, normal fasting: 70-100 mg/dL = 3.9-5.6 mmol/L.
Divide by 38.67. 200 mg/dL = 5.17 mmol/L. Target: <200 mg/dL = <5.17 mmol/L. Furthermore, HDL target: >60 mg/dL = >1.55 mmol/L.
120/80 mmHg = 16.0/10.7 kPa. Normal: <120/80 mmHg. Hypertension: ≥130/80 mmHg. Furthermore, kPa is the SI unit but mmHg remains the universal clinical standard.
14 stones × 6.35029 kg/stone = 88.9 kg. 1 stone = 14 pounds = 6.35 kg. Furthermore, BMI uses kg and m² — convert to metric for BMI calculation.
Fasting: 70-100 mg/dL (3.9-5.6 mmol/L). 2h after meal: <140 mg/dL (<7.8 mmol/L). HbA1c <5.7% = normal. Furthermore, diabetes diagnosed at fasting ≥126 mg/dL (≥7.0 mmol/L).
