Asphalt Calculator+

Available in the App Store

The Asphalt Calculator+ is an app which consists of calculators and solvers to help contractors and sales people estimate costs, sizes, and materials amount as well as prices.

The calculator produces the volume in both cubic feet and cubic meters, and the tons of asphalt hot mix which is required for the form size entered. The tonnage calculation is specific to asphalt only. This app calculates 1 cubic yard of hot asphalt mix as weighing 2.025 tons, or 4050 lbs.

The Wood Equilibrium Moisture Content calculator is designed to give the calculated equilibrium moisture content of non-living wood, natural or cut, based on the data entered, at or below the fiber saturation point (about 30% moisture content) given the temperature and relative humidity.

The moisture content of wood is directly related to the humidity and temperature of the surrounding air. The equilibrium moisture content (EMC) occurs when the wood has reached a water content equilibrium with its environment and is no longer gaining or losing moisture. The calculation used by the calculator is the one provided by the U.S. Forest Products Laboratory.

Heat Index and Relative Humidity Calculator


Available in the App Store

This is a Universal App which will run on the iPhone, iPod Touch, and iPad.

* Featured by Apple in ‘What’s Hot’ in 76 countries(1)

* Now displays automatic weather calculation based on iPhone/iPad localization features with available internet access. Just press the Fetch button.

The Heat Index and Relative Humidity Calculator is a tool for measuring the perceived temperature and relative humidity. Because the body normally cools itself by perspiration, when relative humidity is high, the evaporation rate is reduced, and heat is removed from the body at a lower rate causing it to retain more heat than it would in dry air.

Relative humidity may be defined as the ratio of the water vapor density (mass per unit volume) to the saturation water vapor density, and in the case of this iPhone App it is expressed as a percentage. The air temperature and dew point can be entered as Fahrenheit or Celsius.

The calculator will compute both the relative humidity and the heat indexThe calculator will compute both the relative humidity and the heat index when the values for the air temperature and dew point are entered.

The results can also be emailed through the iphone’s email application. The application is completely compatible with the iPhone OS 3 and later, as well as the iPod Touch.

The heat category is a measurement taken from NOAA’s National Weather Service Heat Index Chart and is used to assist in determining how much caution should be exercised when outdoors for any period of time.

The calculator is the most effective when the temperature is at least 80 °F / 26 °C and the relative humidity is at least 40%.
