如何根据Excel公式计算速度？

Question

I have two columns time and distance , their values 12:00:04 AM and 0.0088626 respectively. In Excel I apply the following formula to find pace:

=IFERROR(A2/(B2*1000)*1000,0)

and the answer is 12:07:31 AM .

I tried to find out pace as per above formula in PHP. I have written PHP code:

$dis = 0.0088626;
$time =  strtotime('12:00:04 AM');
echo date('h:i:s',strtotime(($time / ($dis * 1000) * 1000)));

and the answer is 1:00:00 .

Excel and PHP answers are different.

How I can I achieve this goal?

Answer 1

You need to use the code I showed you earlier to convert PHP's unix timestamps to Excel serialized timestamp values to use in your equation

$dis = 0.0088626;

$x = strtotime("12:00:04 AM");
$y = strtotime("00:00:00");

$time = ($x - $y) / 86400;

$result = ($time / ($dis * 1000) * 1000);

Then once you've calculated the result, you need to convert it back from a Excel serialized timestamp value to a unix timestamp so that you can use PHP's date function

$result *= 86400;
echo date('h:i:s A', $result), PHP_EOL;

which displays the answer 12:07:31 AM
