Maths Weakness

[chad07]

Hi Guys,

I feel stupid for asking this..... But how do i work out how much water my tank can hold??? Ummmm im rubbish at Maths, dont know how i passed my exams lol!!

Dimensions: 2.5FT long, 1FT in Width, 1.5FT in height.....

The reason im asking is that im currently cycling my fish with 4 Plattys as some as you may know, and ill soon be adding to it. Just wondered how many fish im limited too with the size of my tank and once i know how much water my tank holds it should become a little clearer.

Please help....

Chad

LoL can't tell you the answer, cause I suck at maths too and have absolutely no idea how to do imperial calculations, only metric, but if you Google "Aquarium Tank Volume" you should be able to find a calculator pretty quickly to tell you what it is.

Hope this helps

Your tank is about 28 gallon.

In case anyone is wondering how to work out the volume of a tank - you multiply the length x the width x the height. You will now have a cubic volume number. I always then use a conversion site (www.onlineconversion.com is great - can do length, volume, just about anything) to convert this to US gallons, litres, UK gallons whatever. It's all there. That site is also good if you know your gallons and want litres, or if you know inches but want centimetres, or vice versa. I often use this for calculating doses for water treatments that frequently vary between litres/gallons.

So, in your case (I'll use inches)

Length - 2.5 feet = 30 inches
Width - 1 foot = 12 inches
Height - 1.5 feet = 18 inches.

30 x 12 x 18 = 6480 cubic inches.

Using onlineconversion.com volume converter for cubic inches to US liquid gallons..
6480 cubic inches = 28.052 Us gallons (rdd1952 was right on the mark too )
If you're interested, using the litre conversion this is also 106.2 litres.

You'd been given the answer but I though you might like to know how to work it out for the future (and anyone else reading )

Also, generally when you're starting out you use the one inch of fish per gallon rule to work out your stocking. I see you're cycling with fish though, so you'll be unable to fully stock straightaway - build slowly with a few fish at a time so your biological filter can handle the increase in bioload.

Don't forget to account for displacement by your gravel and any ornaments you have - this will bring it a bit below the 28 gallons we've calculated (28 is what you're completely empty tank would hold).

Hope this has helped your maths problems

Using onlineconversion.com volume converter

I have onlineconversions bookmarked. It's a must making calculations.

Also (if you wanted to know), to convert from cubic inches to US gallons, divide by 231.

I always use the calculator on the PFK website, they have calculators for eveything, tank volume, stocking density, electricity cost;

I also use www.onlineconversion.com for changing from litres to gallons, feet to inches, etc.
