How to Use Parkland Formula Calculator

  1. Enter patient weight in kilograms.
  2. Enter burn area as percent total body surface area.
  3. Read the 24-hour total, the first 8-hour amount, and the remaining 16-hour amount. Timing is usually counted from the time of burn, not arrival time.

Formula & Theory - Parkland Formula Calculator

Parkland Formula Calculator uses this core formula:

24-hour fluid = 4 × Body weight(kg) × Burn area(%TBSA)
First 8 hours = 24-hour fluid / 2
Next 16 hours = 24-hour fluid / 2

The Parkland formula is an initial crystalloid resuscitation estimate for significant burns. It uses burn size and body weight because larger burns and larger patients require more fluid during the capillary leak phase. Half of the calculated 24-hour volume is front-loaded into the first 8 hours, with the remainder over the next 16 hours. Real burn care titrates fluid to urine output, perfusion, inhalation injury, age, and local protocol.

Use Cases for Parkland Formula Calculator

  • Emergency burn triage when weight and TBSA are known.
  • Teaching why early burn resuscitation is time-sensitive.
  • Cross-checking first-day fluid estimates before specialist burn guidance arrives.
