# What is the formula's are used to convert to meters/second? [closed]

Using mathematica, what are the formula's/methods available to convert the following per hour intervals into meters per second (using meters/s from light speed):

• Kilometer
• Mile (US)
• Mile (Nautical)
• Feet

The result should be decimal form of each interval with no E+/- in the float section.

• The question does not concern the technical computing software Mathematica by Wolfram Research. Please see the help center to find out about the topics that can be asked here.
If this question can be reworded to fit the rules in the help center, please edit the question.

This question appears to be off-topic because it is not about the Mathematica environment. –  ciao Apr 14 '14 at 0:07

Adjusted question to be mathematica specific. –  Sanuel Jackson Apr 14 '14 at 0:51

I am assuming that you are interested in the code functions within Mathematica For example To get miles in kilometers,

UnitConvert[Quantity[1, "Miles"], "Kilometers"]


This will return

In[11]:= UnitConvert[Quantity[1, "Miles"], "Kilometers"]

Out[11]= 6336/3937, "Kilometers"


Also , tried more complicated units:

In[15]:= UnitConvert[Quantity[1, "Nautical Miles / hour"], "meters / second"]

Out[15]= 4826/9375 Meters/Seconds

In[13]:= UnitConvert[Quantity[1, "Miles / hour"], "Kilometers / second"]

Out[13]= 44/98425 Kilometers/Seconds


To have the answer in decimal form just put the entire function inside N[]

    In[14]:= N[ UnitConvert[Quantity[1, "Miles / hour"], "Kilometers / second"]]

Out[14]= 0.000447041, Kilometers/Seconds

In[17]:= N[UnitConvert[Quantity[1, "Nautical Miles / hour"], "meters / second"]]

Out[17]= 0.514773 Meters/Seconds


You may replace the units to whatever units you want. I will suggest you to visit the site http://www.wolframalpha.com/ This is a simple linguistic based input form that will give you results using common language.

Although I wasn't searching for a Mathematica solution, this is definitely an excellent solution given the above scenario. I will rephrase the question as I believe this is a keeper for the answers. –  Sanuel Jackson Apr 14 '14 at 0:49
