## Answer

Convert to lux first (EV native units are metric); lux=2.5*2EV and.... FC=lux/10.7639 or.... FC=0.2323*2EV Example: EV=10, lux= 2.5*210, 210= 1024, so.. 2.5*1024= 2560lux, or.. 0.2323*1024=238FC for non-math types 2^4 is the same as 24= 2 raised to the power of 4.. e.g. 24= 2*2*2*2=16

### How to convert lowercase to uppercase in Excel 2010?

You can use the UPPER function. You can have text that is in
lower case in one cell be shown as uppercase in another. If you
want to convert the text in place, then you could first put a
formula it into a second cell to convert it. The you could copy
that and do a Paste Special and choose values and paste it onto the
original text. So, you could have the original text in A2. In A3
you could put the following formula:
=UPPER(A2)
Then copy what is in cell A3 and do a Paste Special choosing
values into A2.

### How do you test formulas in Excel?

You can use values that you know what result you expect to get
and then see does the formula give the correct result. You can use
values that test different aspects of a formula, like values that
fit criteria for the formula and ones that don't. Just because a
formula gives the correct answer for some values, it doesn't always
mean it will for all values, so it is important to test it. You can
use the Evaluate Formula to test formulas and see what they do and
find any errors. That is particularly useful for finding problems
in more complex formulas.

### How do you make graph from an equation in Excel?

You need to first convert the equation into a formula. Then
create a set of points by copying the formula and using different
values to create your points. Once you have them, you can select
them and pick a chart, using the Scatter, also known as an XY
chart. Say your equation was x2+5=y, then your formula could be in
B2 and use the value x, say starting from cell A2. The formula
would be:
=A2^2+5
In column A you would start to put in the values for X. When the
formula in B2 is copied down it would work out the values for y.
Then select them and start the Chart Wizard.

### What is the purpose of using Data Tables?

In Excel it allows you to do analysis based on a formula having
one or two values changed to produce a table of various results. It
will take values from the first row and first column and use them
in a formula. The initial formula is in the cell on the first row
and first column, in other words the top left cell of the table.
Whatever the formula does, it then uses the values to fill the
table. So say you put a formula in the top corner cell which adds
two cells. Then you would use the first value on each row and
column of the table as values for the formula.
