Laboratory & Conversions
10 calculators · lipids, urea/creatinine, SI units, weight, length, temperature
Here you will find conversion and laboratory calculators: mg/dl ↔ mmol/l, µmol/l ↔ mg/dl, mEq ↔ mmol ↔ mg and an SI unit converter with factors according to Kratz et al. (NEJM 2004) and the AMA Manual of Style, as well as kg ↔ lb, cm ↔ inch and °C ↔ °F. In addition there are LDL cholesterol according to Friedewald and non-HDL cholesterol with the cut-offs of the NHLBI expert panel 2011, as well as the BUN-creatinine ratio. They are intended for the quick conversion and interpretation of laboratory values in children. Each calculator states its formula and sources.

Frequently asked questions
How do I calculate LDL cholesterol according to Friedewald?
The LDL cholesterol according to Friedewald calculator computes LDL = total cholesterol − HDL − triglycerides/5 (mg/dl) or /2.2 (mmol/l). It also outputs non-HDL cholesterol and classifies both values according to the NHLBI cut-offs 2011 for children and adolescents.
How do I convert creatinine from µmol/l to mg/dl?
The µmol/l ↔ mg/dl calculator converts creatinine, bilirubin, uric acid, iron, ammonia, trace elements and drug levels between µmol/l and mg/dl or µg/dl and µg/ml. Further analytes are covered by the laboratory SI unit converter.
How do I convert mEq to mmol and mg?
The mEq ↔ mmol ↔ mg calculator uses mmol = mEq ÷ valence and mg = mmol × molar mass. It covers sodium, potassium, chloride, bicarbonate, calcium, magnesium, sulfate and phosphate.
