Is there a site to do conversions of measurements

In summary, the conversation revolves around the topic of learning how to convert measurements from one unit to another. The participants discuss the importance of understanding the concept of multiplying by the identity 1 for all conversions, rather than relying on tables or memorization. The conversation also touches on the need to know the density of a substance in order to convert between grams and liters. A site is mentioned that claims to have over 800 conversions, but it is noted that it does not teach the concept. The conversation ends with the participants expressing their gratitude for the help and wishing each other goodnight.

Is there a site that teaches how to do conversions of measurments. More specificly I need one that teaches coversion between different measurements like gallons to cubic inches or square feet to millimeters or grams to meters LOL if there is such a thing lol

I stongly believe that all conversions should be taught as multiplication of a given quantity by the identity, 1. There are countless ways to write 1 as the ratio of any two equals. For example to convert feet to inches

[tex] 3 feet = 3 feet * \frac{12 inches}{1 foot} = 36 inches[/tex]

This can be extended to changes of measuring systems

[tex] 3 feet = 3 feet * \frac{12 inches}{1 foot} * \frac{2.54 cm}{1 inch} = 91.44 cm[/tex]

All conversions can be done by multiplying by appropriate representations of 1. One should never have to think about when to divide and when to multiply. The units tell us which way to form the numerator and denominator of the fraction equal to 1.

Cool I get how to go from say grams to kilograms Its just when it goes from one measurement like grams to say liters. They boggles the mind LOL.

Wow that's a nice site but it does not teach it. I would have to sneak that in and cheat on my math test LOL And I don't have time to memorize 800 conversions LOL

I hate tables like the one posted. I would avoid any table that has no equal signs I want to see

2.54 cm = 1 inch
1 mile = 5280 feet
1 liter = 1000 cm^3

etc etc etc

Grams to liters only makes sense if you know the density of a substance involved. Then you form a conversion fraction from a known ratio.

mass = density * volume

For water density = 1 gm/cm^3

mass of water = (1gm/cm^3)*volume of water
