Biology Body Surface Area (Mosteller)

An anthropometric estimate used in study problems. Not dosing or clinical advice; distinct from BMI.

BSA (m²) = square root of (cm × kg ÷ 3600).

Tip: Keep “Height (cm)” and “Weight (kg)” on the same basis (units, period, and definition) before you calculate.

The Mosteller formula estimates body surface area from height in centimeters and mass in kilograms.

Enter height (cm) and weight (kg) for the study example.

Understanding Biology Body Surface Area (Mosteller)

How we calculate. BSA (m²) = square root of (cm × kg ÷ 3600). See our methodology and accuracy policy .

Real-world scenario: A typical Biology Body Surface Area (Mosteller) case uses height (cm) 175 and weight (kg) 70. Enter the same figures below to reproduce the worked path.

What is Biology Body Surface Area (Mosteller)?

An anthropometric estimate used in study problems. Not dosing or clinical advice; distinct from BMI.

  • Height in cm
  • Weight in kg
  • Educational estimate

The Formula

BSA (Mosteller)
BSA = √((height_cm × weight_kg) ÷ 3600)

Worked Example

Scenario: Height 175 cm; weight 70 kg.
Step 1: 175 × 70 = 12,250
Step 2: 12,250 ÷ 3600 ≈ 3.4028
Step 3: √3.4028 ≈ 1.8447
Answer: BSA is approximately 1.84 m².

Common Use Cases

  • Homework: physiology worksheets
  • Study: compare with BMI page
  • Lab: formula checks

Pro Tips

  • Don’t use for medical dosing
  • cm not meters
  • BMI is a different formula
ScenarioWhen to use
Percent of a numberFinding a part of a whole (tax, tip, score)
Percent changeComparing old vs new values

Limitations: Biology Body Surface Area (Mosteller) results are educational biology study aids—not medical diagnosis, clinical advice, or ecological management guidance. Confirm formulas and units with your textbook or instructor.

Common mistakes

  • Swapping part and whole: The denominator must be the full total, not a subset.
  • Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
  • Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
