Barom.Press: Estimate Barometric Pressure

Description

Function to estimate barometric pressure based on altitude.

Usage

Barom.Press(elevation.m, units = "atm")

Arguments

elevation.m

Elevation in meters above sea level.

units

Output units for barometric pressure must be one of: "atm", "kpa", or "mmHg".

Value

Returns numeric object of barometric pressure in specified units.

Details

This is just a simple conversion function. Plug and chug, as they say...
