Algae math ........do these # 43

Here are some conversions that I have come across and they have come in handy when 'working-the-numbers".

3.78 Liters = 1 gallon
7.48 gallons = 1 cu.ft.

454 grams = one lb.
1kg. = 2.2046 lbs

2,230 lb. = 1 metric ton
2,000 lb. = 1 ton

2.8 lbs of CO2 = 1 lb. dry algae

(this varies from 1.7 to 2.8, I use 2.8 in my numbers.

2.8 tons CO2 = 1 ton dry algae

1 lb CO2 = 8.741 scf
1 gal CO2 = 74.04 SCF
1 gal CO2 = 8.47 lbs.

Cu. ft. CO2 X .12342 = lbs. CO2
Lbs. CO2 divide by .12342 = cu. ft. CO2
CO2 weighs 1.96 kg. per 1 cubic meter
1 cu. meter of volume can hold 1.96 kg. CO2
1 cu. ft. = 0.02831 cu. meter
1 cu. meter = 35.314 cu. ft.

What do you think?? I have more.

    Very interesting and very useful.

    A couple of observations:

    ==2.8 lbs of CO2 = 1 lb. dry algae ==

    1.8 lbs of CO2 = 1 lb. dry algae - this is what has been accepted figure, not just for algae biomass, but for most biomass, it is taken as around 1.6-1.8

    Once again, nice data. Thanks!

    Very nice post. I was also wondering where 2.8 tons of CO2 = 1 ton of dry mass comes from? It this data found with strains of algae with extrememly high hydrocarbon content?

    I am reasonably good in maths. But poor in algae culture. can some one send the maths class above in an xl sheet by email to me.
    My email is

    I dont understand the need for so many zeros ie 0000

    Dear FOA,

    Is anyone out there working on this algae problem?

    Do you need a little help to get started? Ask some questions, please.

    Dear Alan,

    These conversions are very useful for me. But I have an inquiry. Does the OOOO refer to something? What is OOOO?
    Thanks
    Have a nice day

    000 has no significance, basically used to separate things....
