## Overview

Glucose Unit Converter converts a blood glucose value between mg/dL and mmol/L using the factor 0.05551. Enter the value, source unit, target unit, and optional decimal precision to receive a JSON result with the converted value and calculation method. This tool is for reference and is not medical advice.

## Inputs

- **Value** (number): The blood glucose value to convert.
- **Source Unit** (select): The unit of the input value.
- **Target Unit** (select): The unit to convert into.
- **Decimal Places** (number)

## When to use

- Convert a glucose meter or lab result from mg/dL to mmol/L.
- Convert a mmol/L reading to mg/dL for comparison with another report.
- Standardize glucose values when reviewing diabetes, fasting glucose, or hypoglycemia information.

## How it works

- Enter the blood glucose value as a number.
- Choose the input unit: mg/dL or mmol/L.
- Choose the target unit: mg/dL or mmol/L.
- Set the number of decimal places from 0 to 8, then view the converted result and method.

## Use cases

- Compare blood glucose readings reported in different unit systems.
- Translate fasting glucose or hypoglycemia values for educational and reference purposes.
- Prepare consistently formatted glucose values for clinical notes, research, or lab-result review.

## Frequently asked questions

### Which glucose units does this converter support?

It converts between mg/dL and mmol/L.

### What conversion factor does it use?

It uses 0.05551: mg/dL × 0.05551 = mmol/L, and mmol/L ÷ 0.05551 = mg/dL.

### Can I choose the number of decimal places?

Yes. You can choose from 0 to 8 decimal places; the default is 2.

### What does the result include?

The JSON result includes the input units, conversion factor, converted value, category when provided, and calculation method.

### Is this converter medical advice?

No. It performs a unit conversion only. Discuss glucose results and treatment decisions with a qualified healthcare professional.

PAO₂ = FiO₂×(P_atm−47) − PaCO₂/0.8; A-a = PAO₂ − PaO₂. Normal ≈ (Age+10)/4. Elevated → V/Q mismatch, shunt, diffusion impairment. Derived from StatPearls, LITFL, Cornell PICU, and Martin 1999.

VD may be supplied or estimated as ~2 mL/kg body weight. Normal resting ~4–6 L/min; low → hypercapnia, high → hypocapnia. Derived from West, LITFL, StatPearls, and Radford 1955. Not medical advice.
- [Apgar Score (Newborn 1 & 5 min)](https://elysiatools.com/en/tools/apgar-score): Calculate the Apgar score to assess newborn condition at 1 minute and 5 minutes after birth. Five signs are each scored 0–2 at both time points: Appearance (skin color), Pulse (heart rate), Grimace (reflex irritability), Activity (muscle tone), and Respiration. Each time point totals 0–10. Interpretation: 7–10 reassuring; 4–6 moderately abnormal (may need assistance); 0–3 critically low (immediate resuscitation). The tool reports both the 1-min and 5-min scores, the change (delta), and per-time-point interpretation. A 5-min score, and especially the change from 1 to 5 min, indicates response to resuscitation; persistent low 5-min scores warrant continued resuscitation and reassessment at 10 min. Derived from Apgar 1953, reaffirmed by ACOG/AAP. The Apgar is a physiologic snapshot at a moment in time and is not, by itself, a marker of asphyxia or long-term neurologic outcome.
