Heater Size Calculator
Enter Tank Gallons:

Enter Temperature Change Required (tank temperature minus room temperature):

Heater(s) size needed:

*Always unplug heaters before working on your aquarium! Please note that these heater size recommendations are approximations. Tank wall thickness and whether or not you use a lid or top on your aquarium could affect the heater size needed.

Chiller Size Calculator
Enter Tank Volume In Gallons:

Enter Temperature Drop Needed:

BTU's:
Chiller size needed in HP (horsepower):

*The formula used for calculating chiller size is: volume in gallons * 8.34 weight of 1 gallon of water * temperature pull down needed * 20% padding factor. It's better to use an oversized chiller (hence the 20% padding factor in the calculation) than an undersized one to ensure it lasts longer and doesn't have to work as hard and other factors that could impact the efficiency of the unit such as ambient room temperature.

Convert Fahrenheit to Celsius
Enter °F:
= °C
Convert Celsius to Fahrenheit
Enter °C:
= °F

Convert Gallons to Liters
Enter Gallons:
= Liters
Convert Liters to Gallons
Enter Liters:
= Gallons

Convert Inches to Centimeters
Enter Inches:
= Centimeters
Convert Centimeters to Inches
Enter Centimeters:
= Inches

Convert UK Gallons to US Gallons
Enter UK Gallons:
= US Gallons
Convert US Gallons to UK Gallons
Enter US Gallons:
= UK Gallons

Convert Meters to Feet
Enter Meters:
= Feet
Convert Feet to Meters
Enter Feet:
= Meters

Convert Meq/L to dKH CaCO3 (ppm)
Enter Meq/L:
= dKH and
CaCO3 (ppm)
Convert dKH to Meq/L and CaCO3 (ppm)
Enter dKH:
= Meq/L and
ppm CaCO3
Convert CaCO3 (ppm) to Meq/L and dKH
Enter CaCO3:
= Meq/L and
dKH
