Speed check site?

[yankee flyer]

Hello Guys

There used to be a site that had an automatic program to convert time and distance to miles per hour in all scales. Between hard drive crashes and new computer I have lost the address . Does anyone still have the site? It was very convenient because you could use any distance you wanted.

Thanks

Lee,

You could easily recreate that in Excel or any database program that will handle equations.  I'd be more than glad to make one up for you, if you'd like.  (THIS time with the correct equation - See this thread for explanation. )  I have Excel 2007/2010.

Let me know...

Hey Tom

That would be great.    I guess Algebra hasn't changed since 1956.   The formula is probably all I would need for 1:87.

Thanks

go to Western Reserve Division, click articles and look for speed chart

Lee,

Here's the formula:

V[elocity] = D[istance]/T[ime] or MPH = ft./sec.

Ex.
Distance/Time		Total	Convert to mi./hr.		HO	TOTAL
(ft.)	(sec.)	(ft./sec.)	x	÷	x	sMPH
1	3	0.33	3,600	5,280	87.1	19.80

In Excel all I have to do is plug in the distance and time and it automatically calculates it.

Hope that helps...

Here's another one for the same distance and time values above but for Z- thru G-scale:

Distance/Time		Total	Convert to mi./hr.		Convert to sMPH
(ft.)	(sec.)	(ft./sec.)	x	÷	Z	N	TT	HO	S	O/O-27	G
1	3	0.33	3,600	5,280	50.00	36.36	27.27	19.80	14.55	10.91	5.11
					(220:1)	(160:1)	(120:1)	(87.1:1)	(64:1)	(48:1)	(22.5:1)

Thanks

The formula works like a charm. With a 4 decimal answer I may have to get a better stop watch.
