Fahrenheit - Centigrade Conversion
Convert temperatures from Fahrenheit to Centigrade or from Centigrade to Fahrenheit. Click the "Clear Conversion Results" button to clear all form fields.
Carbonate Hardness Unit Conversion
Carbonate hardness, or carbonate alkalinity is a measure of the alkalinity of water caused by the presence of carbonate (CO2− 3) and bicarbonate (HCO− 3) anions. Convert carbonate hardness as parts per million (ppm or mg/L), degree KH (dKH) or Milliequivalents per liter.
Liquid Measurement Conversions
Convert US gallons to liters, pint to liters, quart to liters, drops to milliliters, teaspoon to milliliters, tablespoon to milliliters and fluid ounces to milliliters.
Water Hardness Unit Conversion
Calcium and magnesium dissolved in water are the two most common minerals that make water "hard." The hardness of water is referred to by three types of measurements: grains per gallon, milligrams per liter (mg/L), or parts per million (ppm).
Inches to Centimeters Conversion
Many aquariums and aquarium decor is measured in inches or centimeters. Use this conversion tool to convert measurements from inches to centimeters or from centimeters to inches.
