About this tool
Convert lab report units: blood glucose and cholesterol between mg/dL and mmol/L, creatinine, haemoglobin, bilirubin, vitamin D, blood pressure and clinical body weight.
Pick the lab value, enter the number from your report and see it in the other unit, with the conversion factor shown. This page brings together 8 separate clinical unit converter pages (Bilirubin, Blood sugar, Blood pressure, Cholesterol, Body weight, Creatinine, Haemoglobin, Vitamin D) so you can compare them without hunting for the right one.
Open Clinical Unit Converter on AltFTool — it loads instantly in your browser.
Choose your lab value at the top: Bilirubin, Blood sugar, Blood pressure, Cholesterol and 4 more. On a phone it is a drop-down list.
Fill in the clinical unit converter for that lab value; each of the 8 options keeps its own rules, data and defaults.
Read the result, then switch lab value to compare. The page link keeps your lab value (?v=bilirubin), so you can bookmark or share it.
Bilirubin, Blood sugar, Blood pressure and the rest sit behind one picker, so switching lab value takes a tap instead of a new search.
Every lab value keeps its own rules, numbers and defaults rather than one generic template.
The link remembers the lab value you picked, so a bookmark or a shared link opens straight on it.
8: Bilirubin, Blood sugar, Blood pressure, Cholesterol, Body weight, Creatinine, Haemoglobin, Vitamin D. Pick one at the top of the tool; the page link updates (for example ?v=bilirubin) so you can bookmark or share that exact view.
Multiply by 17.1. So 1.2 mg/dL is about 20.5 µmol/L and 3.0 mg/dL is about 51 µmol/L. Divide by 17.1 to convert micromoles per litre back to mg/dL.
Divide the mg/dL value by 18.0182. For example 126 mg/dL ÷ 18.0182 = 7.0 mmol/L. To go the other way, multiply mmol/L by 18.0182: 5.5 mmol/L × 18.0182 = 99 mg/dL.
Multiply mmHg by 0.133322387415 to get kPa, or divide kPa by that factor to go back — which is the same as multiplying kPa by 7.50062. So 120 mmHg is 16.0 kPa and 80 mmHg is 10.7 kPa.
Divide the mg/dL value by 38.67. So 200 mg/dL total cholesterol is 5.2 mmol/L, and 100 mg/dL LDL is 2.6 mmol/L. Multiply by 38.67 to go the other way.
Multiply pounds by 0.45359237, the exact definition of the international avoirdupois pound. Dividing by 2.2 instead is about 0.2 percent out — small for an adult, but roughly 7 g on a newborn weight, which matters on a growth chart.
Multiply by 88.4. So 1.0 mg/dL is 88.4 µmol/L and 1.2 mg/dL is 106 µmol/L. Divide by 88.4 to convert micromoles per litre back to mg/dL.
Multiply by 0.6206. So 14 g/dL is 8.7 mmol/L and 12 g/dL is 7.45 mmol/L. Divide by 0.6206 to convert mmol/L back to g/dL. The factor is based on the haemoglobin monomer, which is why it differs from the factors used for other blood tests.
Multiply the ng/mL figure by 2.496 to get nmol/L, and divide by 2.496 to go the other way. The factor comes from the 400.64 g/mol molar mass of 25-hydroxyvitamin D3, so 30 ng/mL is 74.9 nmol/L and 20 ng/mL is 49.9 nmol/L. Many reports round the factor to 2.5.
