Tool usage guide
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.
Background
A bilirubin result is reported as 2.5 mg/dL, but the receiving reference uses µmol/L.
Problem
Convert the value accurately while retaining two decimal places.
How to use
Enter 2.5 as Value, select mg/dL as Source Unit, select µmol/L as Target Unit, and set Decimal Places to 2.
value: 2.5; sourceUnit: mgdl; targetUnit: umol; decimalPlaces: 2Outcome
The result is 42.75 µmol/L, calculated as 2.5 × 17.1.
Background
A neonatal bilirubin measurement is recorded as 340 µmol/L, while another document uses mg/dL.
Problem
Express the same measurement in mg/dL for consistent documentation.
How to use
Enter 340 as Value, select µmol/L as Source Unit, select mg/dL as Target Unit, and set Decimal Places to 2.
It uses 17.1: µmol/L = mg/dL × 17.1, and mg/dL = µmol/L ÷ 17.1.
Yes. Enter the reported value for total, direct, or indirect bilirubin; the conversion uses the same unit factor.
The tool converts between mg/dL and µmol/L.
Yes. Set Decimal Places from 0 to 8. The default is 2 decimal places.
No. It only converts units. Discuss bilirubin results and clinical decisions with a qualified healthcare professional.
value: 340; sourceUnit: umol; targetUnit: mgdl; decimalPlaces: 2Outcome
The result is 19.88 mg/dL, calculated as 340 ÷ 17.1.
