nutritional goal - water??
 
Any suggestions?

I want to have a water nutritional goal but when I try to enter it, the system only gives the option of grams. Is there any way to change that to oz? How do you keep track of water grams?

Thanks in advance

Hmm--I don't have FitDay PC, I just use the on-line version, which gives one several choices for water volume, including cups, ounces, grams, etc.

If you can't enter ounces or cups, I guess you'd have to convert. Google kindly informs us that:

1 gram = 0.0352739619 ounces

There are also numerous on-line converters.

Regards,
Michael

I just looked at that today and discovered that 1 gram of water is equal to 1 ml. of water. All you have to do is make the conversion from standard to metric. You can do that simply by Googling for a conversion tool online.

Once you have it set up, you can enter your daily water intake in oz or ml and it automatically coverts for you.

so 1gm h2o = 1mL h2o?

and

30ml h2o = 1fl oz h2o?

i don't think 1gm of water = 1ml because...

i put into my food log that i drank 1 fl oz of water...and it says my actual intake of water in grams on the custom nutrition page is 293.8g.

so this is what i got when I did the math: 1 gram = 0.0034 ounces

i wonder why google says 1 gram = 0.0352739619 ounces. I'd assume google is correct and fitday is wrong...can someone clarify?

and rainbow24, i believe, is incorrect . 1gm does NOT equal 1mL when it comes to water

OK i think i figured it out. google's math is correct but water is measured in FLUID OUNCES not ounces! so...

1 gram of water = 0.0056497175 fluid ounces (177g in a fluid ounce)

so 8 fl oz of water = ~1416 grams ?

fitday is still incorrect as it says 1 fl oz of water = 293.8g

i am really confused...another conversion site online says 1 fl oz = ~29g so 8 fl oz = 236 grams... which is correct?:

1 fl oz = 28.35g (convertunits.com)
1 fl oz = 293.8g (fitdays custom nutrition goal page)
1 fl oz = 177g (wikianswers)
1 fl oz = 29.57g (convert-me.com)

Maybe its a FitDayPC thing.

Using the online Fitday when I log in 1 fl. oz of water I get 29.6 g in the nutrition tab, which is consistent with the conversion from google 1 fluid ounce = 29.5735296 mL and rainbow is right 1 g of water is equal to 1 ml of water.

So let's say you want your goal to be 100 oz of water, that will be 2960 g in the goal (roughly 3 liters of water which is correct).

Hope this helps.
