**Project:** Measurements and Units

**Objective:** To convert a measurement from a unit to another unit.

**Measurement:** Mass

**Given Unit:** Customary unit (Ounce)

**To Convert to:** Metric unit (Gram)

**Container Used:** Soap

**Please look at the bottom left corner.**

Convert $4.25\:oz$ to $g$

__From Given Tables:__

$
1\:lb = 16\:oz \\[3ex]
1\:lb = 453.59237\:g \\[3ex]
1\:lb = 1\:lb \\[3ex]
\implies 16\:oz = 453.59237\:g \\[3ex]
Let\:\:p = mass\:\:of\:\:4.25\:oz\:\:in\:\:g \\[3ex]
\underline{Second\:\:Method:\:\:Proportional\:\:Reasoning\:\:Method} \\[3ex]
$

$oz$ | $g$ |
---|---|

$16$ | $453.59237$ |

$4.25$ | $p$ |

$ \dfrac{p}{4.25} = \dfrac{453.59237}{16} \\[5ex] Multiply\:\:both\:\:sides\:\:by\:\:4.25 \\[3ex] 4.25 * \dfrac{p}{4.25} = 4.25 * \dfrac{453.59237}{16} \\[5ex] p = \dfrac{4.25 * 453.59237}{16} \\[5ex] p = \dfrac{1927.76757}{16} \\[5ex] p = 120.485473 \\[3ex] p \approx 120\:g...rounded\:\:to\:\:the\:\:nearest\:\:whole\:\:number \\[3ex] \therefore 4.25\:oz \approx 120\:g \\[3ex] $ This confirms the quantity in $g$ (in parenthesis) in the soap container.

**Project:** Measurements and Units

**Objective:** To convert a measurement from a unit to another unit.

**Measurement:** Volume

**Given Unit:** Customary unit (Fluid Ounce)

**To Convert to:** Metric unit (Milliliters)

**Container Used:** Water

**Please look at the top center corner.**

Convert $16.9\:fl\:\:oz$ to $mL$

__From Given Tables:__

$
1\:L = 0.264\:gal \\[3ex]
1\:gal = 4\:qt \\[3ex]
1\:qt = 4\:cups \\[3ex]
1\:cup = 8\:fl.\:oz \\[3ex]
$
Based on what we were given:

Let us first convert it to liters ($L$)

Then, we will convert from liters ($L$) to milliliters ($mL$)

$
\underline{First\:\:Method:\:\:Unity\:\:Fraction\:\:Method} \\[3ex]
16.9\:fl\:oz\:\:to\:\:L \\[3ex]
Set\:\:it\:\:up\:\:and\:\:check\:\:to\:\:make\:\:sure\:\:it\:\:is\:\:correct \\[3ex]
16.9\:fl\:oz * \dfrac{.....L}{.....gal} * \dfrac{.....gal}{.....qt} * \dfrac{.....qt}{.....cup} * \dfrac{.....cup}{.....fl.\:oz} \\[5ex]
16.9\:fl\:oz * \dfrac{1\:L}{0.264\:gal} * \dfrac{1\:gal}{4\:qt} * \dfrac{1\:qt}{4\:cup} * \dfrac{1\:cup}{8\:fl.\:oz} \\[5ex]
= \dfrac{16.9 * 1 * 1 * 1 * 1}{0.264 * 4 * 4 * 8} \\[5ex]
= \dfrac{16.9}{33.792} \\[5ex]
= 0.500118371\:L \\[3ex]
Convert\:\:0.500118371\:L\:\:to\:\:mL \\[3ex]
\underline{First\:\:Method:\:\:Unity\:\:Fraction\:\:Method} \\[3ex]
Set\:\:it\:\:up\:\:and\:\:check\:\:to\:\:make\:\:sure\:\:it\:\:is\:\:correct \\[3ex]
0.500118371\:L * \dfrac{.....mL}{.....L} \\[5ex]
= 0.500118371\:L * \dfrac{1\:mL}{10^{-3}\:L} \\[5ex]
= 0.500118371\:L * \dfrac{1\:mL}{0.001\:L} \\[5ex]
= 500.118371\:mL \\[3ex]
500.118371\:mL \approx 500\:mL \\[3ex]
$
This confirms the quantity in $mL$ in the water container.

*
Student: Sir, you could have used the direct conversion from gallons to cups...
and bypass quarts
$
16.9\:fl\:oz * \dfrac{.....L}{.....gal} * \dfrac{.....gal}{.....cup} * \dfrac{.....cup}{.....fl.\:oz} \\[5ex]
16.9\:fl\:oz * \dfrac{1\:L}{0.264\:gal} * \dfrac{1\:gal}{16\:cups} * \dfrac{1\:cup}{8\:fl.\:oz} \\[5ex]
$
Teacher: That is right!
You are correct.
But, what if you were given a table that does not have that direct conversion?
Student: Then, I would use what I was given.
But, in this case; we were given that direct conversion.

**Project:** Measurements and Units

**Objective:** To convert a measurement from a unit to another unit.

**Measurement:** Lengths (Width by Length)

**Given Unit:** Customary unit (in by in)

**To Convert to:** Metric unit (cm by cm)

**Container Used:** Hand Wipes

**Please look at the bottom center corner.**

Convert $5.7\:in\:\:by\:\:7.5\:in$ to $cm\:\:by\:\:cm$

$
Width = 5.7\:in \\[3ex]
Length = 7.5\:in \\[3ex]
$
__From Given Tables:__

$
1\:ft = 0.3048\:m \\[3ex]
12\:inches = 1\:ft \\[3ex]
1\:ft = 12\:inches \\[3ex]
1\:ft = 1\:ft \\[3ex]
\implies 0.3048\:m = 12\:inches \\[3ex]
$
We shall use the First Method to convert the width.

We shall use the Second Method to convert the length.

Use any method(s) you prefer.

$
\underline{First\:\:Method:\:\:Unity\:\:Fraction\:\:Method} \\[3ex]
Convert\:\:the\:\:Width \\[3ex]
5.7\:in \:\:to\:\: cm \\[3ex]
Set\:\:it\:\:up\:\:and\:\:check\:\:to\:\:make\:\:sure\:\:it\:\:is\:\:correct \\[3ex]
5.7\:in * \dfrac{.....m}{.....in} * \dfrac{.....cm}{.....m} \\[5ex]
5.7\:in * \dfrac{0.3048\:m}{12\:in} * \dfrac{1\:cm}{10^{-2}\:m} \\[5ex]
= 5.7\:in * \dfrac{0.3048\:m}{12\:in} * \dfrac{1\:cm}{0.01\:m} \\[5ex]
= \dfrac{5.7 * 0.3048 * 1}{12 * 0.01} \\[5ex]
= \dfrac{1.73736}{0.12} \\[5ex]
= 14.478\:cm \approx 14.5\:cm \\[3ex]
\underline{Second\:\:Method:\:\:Proportional\:\:Reasoning\:\:Method} \\[3ex]
Convert\:\:the\:\:Length \\[3ex]
Let\:\:p = length\:\:of\:\:7.5\:in\:\:in\:\:m \\[3ex]
Let\:\:c = length\:\:of\:\:p\:m\:\:in\:\:cm \\[3ex]
$
Based on what we were given:

We need to first convert to meters ($m$)

Then, we will convert from meters ($m$) to centimeters ($cm$)

__From Given Tables:__

$
1\:ft = 0.3048\:m \\[3ex]
12\:inches = 1\:ft \\[3ex]
1\:ft = 12\:inches \\[3ex]
1\:ft = 1\:ft \\[3ex]
\implies 0.3048\:m = 12\:inches \\[3ex]
1\:cm = 10^{-2}\:m \\[3ex]
1\:cm = 0.01\:m
$

$in$ | $m$ |
---|---|

$12$ | $0.3048$ |

$7.5$ | $p$ |

$ \dfrac{p}{7.5} = \dfrac{0.3048}{12} \\[5ex] Multiply\:\:both\:\:sides\:\:by\:\: 7.5 \\[3ex] 7.5 * \dfrac{p}{7.5} = 7.5 * \dfrac{0.3048}{12} \\[5ex] p = \dfrac{7.5(0.3048)}{12} \\[5ex] p = \dfrac{2.286}{12} \\[5ex] p = 0.1905\:m \\[3ex] $

$m$ | $cm$ |
---|---|

$0.01$ | $1$ |

$0.1905$ | $c$ |

$ \dfrac{c}{1} = \dfrac{0.1905}{0.01} \\[5ex] c = 19.05\:cm \approx 19.1\:cm $

The results confirm the quantities in $cm$ in the hand wipe container.
