About this tool
Convert mg/dL to mmol/L instantly. Free, bidirectional, and fully in-browser.
1 milligram per deciliter equals 0.0555 mmol/L — enter any milligram per deciliter value to convert it to mmol/L instantly. This Milligram per deciliter to Millimole per liter converter is a client-side tool: it applies a single multiplication (mmol/L = mg/dL × 0.0555) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert mmol/L back to mg/dL. A reference table lists common milligram per deciliter values already converted, and nothing you enter is sent to a server.
Open Milligram per deciliter to Millimole per liter Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Milligram per deciliter field.
Read the equivalent in mmol/L in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert mmol/L to mg/dL.
The result updates as you type, and the swap button flips the conversion to millimole per liter → milligram per deciliter without reloading.
The conversion uses the precise factor (mmol/L = mg/dL × 0.0555), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One milligram per deciliter is 0.0555 mmol/L. Multiply the milligram per deciliter value by 0.0555 to convert. For example, 10 mg/dL = 0.555 mmol/L.
mmol/L = mg/dL × 0.0555. This tool applies it automatically and shows a worked example: 10 mg/dL = 0.555 mmol/L.
Yes. Press the swap button, or type into the millimole per liter field, and the tool converts mmol/L to mg/dL using the inverse of the same relationship.
It uses the standard blood glucose concentration definition (mmol/L = mg/dL × 0.0555), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
