Enter a value for all fields

The **Schlich Body Surface** calculator computes the body surface area of the human body based on the person's weight (w), height (h) and gender (sex) using the Schlich algorithm.

**INSTRUCTIONS:** Choose weight and height units and enter the following:

- (
**w**) Weight of Person. - (
**h**) Height of Person. - (
**sex**) Choose Men or Women

**Body Surface Area (BSA):** The BSA is returned in square meters (m²). However, this can be automatically converted into other area units via the pull-down menu.

BSA is used in physiology and medicine. The default input units are centimeters (cm) for height and kilograms (kg) for weight, and meters squared (m^{2}).

The Schlich Body Surface area formula is:

BSA = 0.000975482 X W^{0.46 }X H^{1.08} (for women)

BSA = 0.000579479 X W^{0.38} X H^{1.24} (for men)

where:

- BSA = Body Surface Area
- W = Weight of Person
- H = Height of Person

**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.

- Body Surface Area Comparison with Averages

- 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..
