## Overview

Convert a serum bilirubin value between mg/dL and µmol/L using the fixed factor 17.1, with control over the number of decimal places. The converter supports total, direct, and indirect bilirubin values and is not medical advice.

## Inputs

- **Value** (number): The bilirubin value (total / direct / indirect) 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 bilirubin result from mg/dL to the SI unit µmol/L.
- Convert a laboratory value from µmol/L to mg/dL for comparison with another report.
- Standardize total, direct, or indirect bilirubin results before reviewing or documenting them.

## How it works

- Enter the bilirubin value in the Value field.
- Select the input unit, mg/dL or µmol/L, as the Source Unit.
- Select the required output unit as the Target Unit.
- Choose the number of decimal places from 0 to 8, then read the JSON conversion result.

## Use cases

- Translate bilirubin results between conventional and SI units in laboratory medicine.
- Compare values reported in different units across adult, pediatric, and neonatal records.
- Prepare clearly formatted bilirubin measurements for clinical documentation or study notes.

## Frequently asked questions

### What conversion factor does the tool use?

It uses 17.1: µmol/L = mg/dL × 17.1, and mg/dL = µmol/L ÷ 17.1.

### Can I convert total, direct, and indirect bilirubin?

Yes. Enter the reported value for total, direct, or indirect bilirubin; the conversion uses the same unit factor.

### Which units are supported?

The tool converts between mg/dL and µmol/L.

### Can I choose the rounding precision?

Yes. Set Decimal Places from 0 to 8. The default is 2 decimal places.

### Is this converter medical advice?

No. It only converts units. Discuss bilirubin results and clinical decisions with a qualified healthcare professional.

- [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.
