The Parkland Replacement Fluids calculator computes the amount of fluids required for the first 24 hours in a burn patient using the Parkland Formula and the patient's weight (mass) and percent of the body surface area burned.
INSTRUCTIONS: Choose units and enter the following:
- (m) Weight of Patient
- (A) Percent of Patients Body Surface Area Covered in Burns. CLICK HERE to calculate percent of body burned.
Replacement Fluids (V): The calculator returns the volume of replacement fluids in liters (L). However, this can be automatically converted to other volume units (e.g. cups) via the pull-down menu.

Burn Surface Area
Wallace Rule of Nines
Rule of Fives (Obese Patients) 
Percent of Burned BodyThe Wallace Rule of Nines can be used to approximate the percent of a patient that is burned. It applies a percent of Body Surface Area, often a multiple of 9, for different body parts as follows:
- (9%) Entire head
- (9%) Complete left arm
- (9%) Complete right arm
- (9%) Entire chest
- (9%) Entire abdomen
- (18%) Complete back
- (1%) Groin
- (18%) Complete left leg
- (18%) Complete right leg
The Rule of Fives can be used to approximate the percent of an obese patient that is burned. It applies a percent of Body Surface Area, and differs from the Wallace Rule of Nines in that it applies a larger portion of the body surface area to the trunk and legs as follows:
- (2%) Entire head
- (5%) Complete left arm
- (5%) Complete right arm
- (50%) Trunk
- (20%) Complete left leg
- (20%) Complete right leg
Body Surface Area (BSA) is the measured or calculated surface area of a human body frequently used in physiology and medicine. For many clinical purposes BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Estimation of BSA is simpler than many measures of volume.

Other BSA Applications
- The BSA Compare function lets you enter a body surface area and choose a demographic (above) to compute the percent compared to the mean.
- Wallace Rule of Nines: This computes a percentage of the human body for burn victims based on percentages allocated to different body parts.
- Rule of Fives: This computes a percentage of the human body for obese burn victims.
- Parkland Replacement Fluid: This compute the volume of replacement fluids needed in the first 24 hours based on the patients weight (mass) and the percent of their body that has been burned.
- BSA Percent: This computes a body surface area based on the total body surface area and a percent..
