Enter a value for all fields

The **Wang Hihara Human Body Surface Area** calculator computes the body surface area of the human body based on the person's mass(BM) and height(BH) using the Wang Hihara formula.

**INSTRUCTIONS:** Choose your preferred mass and height units and enter the following:

- (
**BM**) The mass/weight of the person. - (
**BH**) The height of the person.

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

The Wang Hihara formula is as follows:

`BSA = sqrt((BM * BH)/3537)`

BSA is used in physiology and medicine for both humans and animals. The default input units are centimeters for height and kilograms for mass, and meters squared (m^{2}) for the BSA.

**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.

- 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..
