About

In the field of laboratory medicine, accurate interpretation of concentration units is vital for diagnosis. While many European laboratories utilize Micrograms per Liter (mcg/l), other regions or specific assays (such as pediatric endocrinology) may report in Micrograms per Deciliter (mcg/dl).

This tool performs the necessary volume expansion calculation instantly. It is specifically designed to be lightweight and accessible for healthcare professionals working in hospital environments with limited internet bandwidth. It strictly prevents negative inputs, as biological concentration values cannot be less than zero.

Formulas

A deciliter is one-tenth of a liter. Therefore, a concentration measured per deciliter is ten times more concentrated when expressed per liter.

C_(mcg/l) = C_(mcg/dl) × 10

Frequently Asked Questions

Yes. "mcg" and "ug" are both abbreviations for microgram. "ug" uses the Latin letter u to substitute for the Greek letter mu (µ), while "mcg" is often preferred in handwritten prescriptions to avoid confusion with "mg" (milligram).

You are converting the denominator from a smaller volume (deciliter) to a larger volume (liter). If you have a certain amount of mass in a small cup (dl), you would have 10 times that mass if you had a full bucket (l) of the same liquid.

Yes. The tool includes a print-friendly view feature that formats the calculation clearly for patient files or lab notes.
