Still into the manual methods?
Here is some information to help with that also...

 

1 gallon of fresh water weighs 8.33 pounds
1 cubic foot of water = 7.5 gallons = 37.8 liters

Surface Area:

1 square centimetre = 0.16 square inches
1 square inch = 6.45 square centimetres

Volume:

1 gallon = 3.785 liters
1 liter = 0.264 gallon = 1000 ml = 33.8 fluid ounces = 2.25 lb = 1 kg water
drop = 1/20 ml
ml= 20 drops
teaspoon = 5 ml
tablespoon = 15 ml
fluid ounce = 30 ml

Aquarium Capacity:

L" x W "x H" /231 = number of gallons
L x W x H (cm) /1,000 = number of litres
No. litres x 0.264 = number of gallons

Concentrations:

Parts per thousand (ppt) = ml/L = 3.8 ml/gal
Part per million (ppm)= mg/L = 3.8 mg/gal = ml/1,000 L
1% solution = 38 gm/gal = 38 ml/gal = 10 ml/L

Temperature:

Centigrade or Celsius = (F - 32) x 0.55
Fahrenheit = (C x 1.8) + 32
