Well I'm no cook -- just a wannabee chemist :-))

Ron,

I can not seem to replicate your spreadsheet - any chance of you sending it
to my email address by taking the "NoSpam" out of my address? By the way,
do you like pizza's?

Thank you Guru Swami,

Wazza McG

The same basic formulas that I posted can be used. But since you are
changing
the number of grams per cup depending on the substance, you'll need to
change
those equivalents in a table.

The rewritten formulas (eliminating the 1/3 cups)

A2: Weight in grams
B2 Cups: =ROUNDDOWN(A2/GmPerCup*4,0)/4
C2 Tbsp: =INT((A2-(B2*GmPerCup))/GmPerTbsp)
D2 Tsp: =ROUND((A2-B2*GmPerCup-C2*GmPerTbsp)/GmPerTsp*4,0)/4


GmPerCup: 160 or whatever
GmPerTbsp: =GmPerCup/12.5
GmPerTsp: =GmPerCup/50

Using these formulas, and taking 270 gm @ 160 gm/cup, I get

1.5C 2T 1.5t

That is rounding 't' to the nearest 1/4 tsp (since I have a 1/4 tsp
measure).
It actually calculates to 1.375t

You could also use a lookup table to insert the GmPerCup.

Have a column with the substance and a table with the conversions:

Table H1:K4 And the values for GmPerTbsp and GmPerTsp were generated by
the
same formulas above.

Substance HiGFlour StdFlour Sugar
GmPerCup 160 120 260
GmPerTbsp 12.8 9.6 20.8
GmPerTsp 3.2 2.4 5.2


Then set up the following:

A1: Substance
B1: Cups
C1: Tbsp
D1: Tsp

A2: e.g. HiGFlour
B2: e.g. 270
C2: =ROUNDDOWN(B2/HLOOKUP(A2,$H$1:$K$4,2,FALSE)*4,0)/4
D2:
=INT((B2-(C2*HLOOKUP(A2,$H$1:$K$4,2,FALSE)))/HLOOKUP(A2,$H$1:$K$4,3,FALSE))

E2:
=ROUND((B2-C2*HLOOKUP(A2,$H$1:$K$4,2,FALSE)-
D2*HLOOKUP(A2,$H$1:$K$4,3,FALSE))/HLOOKUP(
A2,$H$1:$K$4,4,FALSE)*4,0)/4


Best,

Hi All,

Oh, I just researched the delemma and I now understand the argument
regarding the amount of teaspoons in a tablespoon due to the difference in
conversions between US, British, Canada and Australia measurements. This
site has a Standard Liquid Measurement -
http://www.ozevillage.com.au/gs/tips...pic=conversion .

a.. 5ml = 1/6fl oz = 1 teaspoon (50 teaspoons in 1 cup)
a.. 20ml = 2/3fl oz = 1 tablespoon (12.5 Tablespoons in 1 cup)
a.. 30ml = 1 fl oz = 1 tablespoon plus 2 teaspoons
a.. 60ml = 2fl oz = 1/4 cup
a.. 125ml = 4fl oz = 1/2 cup
a.. 185ml = 6fl oz = 3/4 cup
a.. 250ml = 8fl oz = 1 cup
a.. 500ml = 16fl oz = 2 cups
a.. 1 litre = 35fl oz = 4 cups

As you can see, I have made some corrections to my initial query.

I know the math in some of the conversions is not brilliant to say the
least, however, I am happy enough to use the above table. I agree with
Ron
Rosenfeld - give the 1/3 and 2/3 of a Cup the flick.

I do own a metric scale, but, it is a real pain having to measure with it
all the time. This is the reason why, High Gluten Flour is 160g for 1
cup
and standard Flour is 120g for 1 cup. Sugar is 250g for 1 cup - the same
as
water. I was hoping to measure 1 cup of an ingedient and then use that to
work out the imperial volume of random measurements eg ;
270g of sugar = 1C, 1T,0t ;
270g of High Gluten Flour is 1 C, 2T,1t.

Where 1C = 1 Cup, 1T = 1 Tablespoon and 1t = 1 teaspoon.

I know this is doosy of an equation, however, I am hoping there is an
excel
guru out there that can shine some light on this.

Regards,

Wazza McG

Hi,

I have been having trouble trying to work out a formula for the
following.

One cup of flour weighs 160g.

If I had 240g of flour I would have 1 1/2 Cups.

Now the hard bit, there are 16 Tablespoons and 48 teaspoons in a cup of
flour.

If I had 270g of flour I want the formula to have an end result of - 1
1/2
C, 2T and 3t - rounded off as close as possible.

In the cup measures, I would only want to use 1/4 C, 1/3 C, 1/2 C, 2/3
C,
3/4 C and 1C and so on. I know 5t should read 1T and 1t, however,
getting
a
formula to work is beyond me at this stage.

If anyone can help, It would be greatly appreciated.

If you could eliminate those pesky 1/3 and 2/3 cup measures, it would be
much
simpler (rounding Tsp to the nearest 1/4 tsp)

With the weight in A2:

Cups B2: =ROUNDDOWN(A2/160*4,0)/4
Tbsp C2: =INT((A2-(B2*160))/10)
Tsp D2: =ROUND((A2-B2*160-C2*10)/3*4,0)/4

If you insist on using those 1/3 and 2/3 cup measures, then the formula
for
Cups becomes more complicated, as I believe you would want the most
accurate
measu

Cups B2:

=MAX(ROUNDDOWN(A2/160*4,0)/4,ROUNDDOWN(A2/160*3,0)/
IF(ABS(A2-(ROUNDDOWN(A2/160*4,0)/4*160+INT((A2-(
ROUNDDOWN(A2/160*4,0)/4*160))/10)*10+ROUND((A2-
ROUNDDOWN(A2/160*4,0)/4*160-INT((A2-(ROUNDDOWN(
A2/160*4,0)/4*160))/10)*10)/3*4,0)/4*3))<ABS(A2-(ROUNDDOWN(
A2/160*3,0)/3*160+INT((A2-(ROUNDDOWN(A2/160*3,0)/3*160))
/10)*10+ROUND((A2-ROUNDDOWN(A2/160*3,0)/3*160-INT((A2-
(ROUNDDOWN(A2/160*3,0)/3*160))/10)*10)/3*4,0)/4*3)),30,3))
