Aquarium Calculators

Available in the App Store

The Aquarium Surface Area & Volume app provides volume, surface area, and weight information so that you can construct your aquarium to your own specifications. All that is needed to be provided for the app is the dimensions of the tank, i.e. width, radius, depth, etc., as well as salinity.

The answers are presented in both US units and metric. The surface area is top the of your aquarium is where the oxygen diffuses into the water. The volume is the maximum amount of water in inches or centimeters as well as gallons or liters the aquarium can hold. The weight is in US pounds or kilograms as the calculated amount of water plus salinity. Salinity defaults to 1.0, but it can be changed and saved per calculation.

The types of aquariums supported are

1. Rectangular Aquarium
2. Hexagon Aquarium
3. Cylinder Aquarium
4. Half Cylinder Aquarium
5. Corner Quarter Cylinder Aquarium

Additionally, there is are the following Converters

1. Area
2. Distance
3. Flow Rate
4. Imperial/US Units to Metric Conversion
5. Metric to Imperial/US Units
6. Pressure Units
7. Temperature
8. Volume
9. Flow Rate (Volumetric: Gallons or Liters)

Temperature Converter for Farenheht/Celsius/Kelvin conversion and a Flow Rate Converter for converting between gallons per minute (gpm), gallons per hour (gph), liters per hour (l/hr), and liters per minute (l/min).

All results can also be emailed through the iphone’s email application using an automatically filled-in email template provided with the app.

All calculations are persistent state and can be saved after closing the app.

Concrete Bags, Footings, Rectangle, & Sono Tube Calculators with Volume from Rainfall Calc

Available in the App Store

* Featured by Apple in the United States in Productivity > New & Noteworthy

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

• Concrete Bags
• Concrete Footings
• Concrete Rectangle
• Concrete Sono Tube

The Water Collection and Rainfall calculators are designed to calculate the potential and factored water supply of any given enclosure by measuring the interior for the collection of water using length, width, and depth in feet, inches, or meters. The surface area is calculated in square feet, square inches, square yards, and square meters, as well as the potential and estimated actual recovery volume is given in cubic feet, cubic meters, gallons, quarts, and liters.

Water may be collected from any surface, and this app assumes a rectangular enclosure and a constant depth where the water is stored to allow use at a later time for non-drinking water utility, for example, flowers and lawns. Because of direct loss and other factors, such as evaporation, there is a percentage of the actual potential that is very close for collected water volume. In moist cool areas, that may be in the range of 85%, or in the case of dry, hot, desert conditions, it is closer to 60%.
