Formula used for creatinine unit conversion
Creatinine unit conversion relies on its molar mass (approximately 113.12 g/mol) and the relationship between mass concentration and molar concentration across mg/dL and µmol/L.
- 1 mg/dL = 10 mg/L = 0.01 g/L.
- Moles/L = (grams/L) ÷ (g/mol).
- µmol/L = moles/L × 106.
Combining these steps for creatinine gives:
1 mg/dL × (0.01 / 113.12) mol/L × 106 ≈ 88.42 µmol/L.
Therefore:
- mg/dL to µmol/L: value (µmol/L) = value (mg/dL) × 88.42
- µmol/L to mg/dL: value (mg/dL) = value (µmol/L) ÷ 88.42
Values are rounded for practicality. Laboratories may adopt slightly different factors; align with local policy.

Normal creatinine levels by age (mg/dL)
Typical reference intervals vary by lab, method, body size, and sex. Always interpret using local ranges and clinical judgment.
| Group | Approximate normal range (mg/dL) |
|---|---|
| Newborns | 0.3 – 1.2 |
| Infants (15 days – 2 years) | 0.2 – 0.4 |
| Children (2 – 12 years) | 0.3 – 0.7 |
| Adolescents | 0.5 – 1.0 |
| Adult females | 0.5 – 1.1 |
| Adult males | 0.6 – 1.3 |
Are creatinine and creatine the same?
No. Creatine is a muscle energy storage compound. Creatinine is its breakdown product, excreted by kidneys. Only creatinine is routinely used to assess kidney filtration.
Quick fixed conversions (mg/dL ↔ µmol/L & mmol/L)
For creatinine: 1 mg/dL = 88.42 µmol/L = 0.08842 mmol/L. Some queries below use “mmol/L” although values are typically reported in µmol/L.
| Query | Converted value | Comment |
|---|---|---|
| Creatinine 1.3 mg/dL to mmol/L | 1.3 mg/dL ≈ 114.95 µmol/L ≈ 0.115 mmol/L | Upper-normal for many adults; check lab range. |
| Creatinine 1.5 mg/dL to mmol/L | 1.5 mg/dL ≈ 132.63 µmol/L ≈ 0.133 mmol/L | Often elevated; requires clinical correlation. |
| 1 creatinine mg/dL | 1.0 mg/dL = 88.42 µmol/L = 0.088 mmol/L | Useful anchor for manual checks. |

Frequently Asked Questions
1. What factor is used to convert creatinine mg/dL to µmol/L?
The calculator uses the standard creatinine factor 1 mg/dL = 88.42 µmol/L, derived from its molar mass (113.12 g/mol). This factor is widely accepted, but always confirm against your laboratory’s documented unit conversion policy.
2. Why do some labs report creatinine in µmol/L instead of mg/dL?
Many laboratories use µmol/L in international systems to align with SI units and standard reporting. This converter lets you instantly switch between µmol/L and mg/dL without manually recalculating each result.
3. Can I use this converter to diagnose kidney disease?
No. This converter is a supportive educational tool only. Kidney disease diagnosis requires full clinical evaluation, serial creatinine values, eGFR formulas, urinalysis, imaging, and specialist interpretation using accredited laboratory measurements and local reference ranges.
4. How accurate is the 88.42 conversion constant?
The 88.42 factor is derived from creatinine’s molecular weight and widely referenced nephrology literature. Small differences (for example 88.4) reflect rounding. Use whichever factor your laboratory or electronic medical record specifies for complete consistency.
5. Should I round creatinine results in clinical practice?
Yes. Match rounding to your lab report, commonly one or two decimals in mg/dL and no more than whole numbers in µmol/L. This keeps results consistent for trending, dosing, and communication.
6. Does creatinine level depend only on kidney function?
No. Creatinine is influenced by muscle mass, diet, hydration, medications, and laboratory method, alongside kidney function. Mildly high values may be benign; persistently abnormal results should always be interpreted by a qualified clinician.
