3. The measure of the force of gravity on the object.
What is it?
Mensuration. It is defined as the branch of geometry that deals with the
measurement of length, area, or volume. It is also the act or process of
measuring.
Calculation. It is a deliberate process that transforms one or more inputs
into one or more results. The term is used in a variety of senses, from
the very definite arithmetical calculation of using an algorithm, to the vague
heuristics of calculating a strategy in a competition, or calculating the chance
of a successful relationship between two people.

Conversion of Weight, Time, Temperature, and Space
Measurement
A. Conversion of Weight
Weight is the measure of the force of gravity on that object. It is a body's
relative mass or the quantity of matter contained by it, giving rise to a downward force;
the heaviness of a person or thing.
Below are the unit conversions of weight (mass):

1 gram (g) = 0.035274 ounces (oz)
1 ounce (oz) = 28.34952 grams (g)
1 kilogram (kg) = 2.20462 pounds (lbs)
1 pound (lb) =
453.59237 grams (g)
1 kilogram (kg) = 35.27396 ounces (oz)
1 pound (lb) =
0.45359 grams (g)
Exercise 1: A group of guests in a hotel has a total luggage that weighs 176
pounds (lbs). Convert the weight of the total weight of the luggage into kilograms.
Solution A: Multiply 176 lbs by using the given conversion factor:
Conversion: 1 kilogram (kg) = 2.2 pounds (lbs)

Exercise 2: Zoey is an employee in the linen and laundry department in a
prestigious hotel. She then gets a 530 grams of detergent powder to be used
in washing hotel linens. The measurement used in procedure in their laundry
task sheets is in pounds (lbs). Help her convert from grams to pounds.
This problem has two ways in getting the measurement needed:
Solution A: Multiply 530 g by using two given conversion factors:
First Conversion: 1 kilogram (kg) = 1000 grams (g)

B. Conversion of Time Measurement
A unit of time or midst unit is any particular time interval, used as a
standard way of measuring or expressing duration. The base unit of time in
the International System of Units (SI) and by extension most of the Western
world, is the second, defined as about 9 billion oscillations of the caesium
atom.
Below are the unit conversions of time measurement:
UNIT
CONVERSIONS
Time Measure
1 minute = 60
seconds
1 hour = 60 minutes
1 day = 24 hours
1 week = 7 days
1 year = 12 months
Exercise 1: Julie works in a hotel for so long. She works in at least 6.5 hours
every shift. She wants to know how many minutes she works in every shift.
Solution A: Multiply 6.5 hours by using the given conversion factor:

Therefore, Andre’s entire shift in cleaning deluxe rooms is 2.3 days.
C. Conversion of Temperature
Degrees Fahrenheit, (developed in the early 1700's by G. Daniel
Fahrenheit), is used to record surface temperature measurements by
meteorologists in the United States. However, since most of the rest of the
world uses degrees.
Celsius (developed in the 18th Century), it is important to be able to
convert from units of degrees Fahrenheit to degrees Celsius.
Kelvin is another unit of temperature that is very handy for many
scientific calculations, since it begins at absolute zero, meaning it has no
negative numbers. (Note: The word "degrees" is NOT used with Kelvin.)
Below are the unit conversions of temperature.

Activity 1- Solve and Convert
Directions: Read, analyze and answer the following equations. Solve and
show your solutions in your TLE Household Services activity
notebook. (5 points each)
1. Convert 412 ounces (oz) of hotel guest baggage to pounds.
2. Convert 23°C of hotel room temperature to Fahrenheit
3. Convert 3,412 hours of work time of the housekeeper employee to days.
RATIO AND PROPORTION
Ratio. It is the quantitative relation between two amounts showing
the number of times one value contains or is contained within the other. In
housekeeping, it would vary based on the type of hotel, and the size of the
rooms.
Notation: Ratio of two values a and b is written as: a:b or a/b or a to b
For instance, the ratio of number of boys in a class to the number of
girls is 2:3. Here, 2 and 3 are not taken as the exact count of the students
but a multiple of them, which means the number of boys can be 2 or 4 or
6…etc and the number of girls is 3 or 6 or 9… etc. It also means that in every
five students, there are two boys and three girls.
Question 1: In a certain hotel, there are 28 guest women and 21 guest
men. What is the ratio of guest men to guest women? What is
the ratio of guest women to the total number of guests in the
hotel?
Solution
:
Guest Men : Guest Women

Women: total number of
guests

=
21:28 (divisible by
7)
3:4
28:49 (divisible by

4:7
Question 2: In a group, the ratio of doctors to lawyers is 5:4. If the total
number of people in the group is 72, what is the number of
lawyers in the group?
Solution:
Let the number of doctors be 5x and the number of lawyers be 4x.
Then 5x+4x = 72 → x=8.
So, the number of lawyers in the group is 4*8 = 32.
Question 3: If the ratio of chocolates to ice-cream cones in a box is 5:8
and the number of chocolates is 30, find the number of icecream cones.
Solution:
Let the number of chocolates be 5x and the number of
ice-cream cones be 8x.
5x = 30 → x = 6
5(6) = 30
Therefore, number of ice-cream cones in the box
8x = 8(6) = 48.
Proportion. It is defined as the comparison of two ratios.
If a: b = c: d, then a, b, c, d are said to be in proportion and
written as
a: b :: c:d
or
a/b=c/d.
a, d are called the extremes and b, c are called the means.
For a proportion a: b = c: d, product of means = product of extremes →
b*c = a*d.
Let us take a look at some examples:
Question 1: In a mixture of 45 litres, the ratio of sugar solution to salt solution
is 1:2. What is the amount of sugar solution to be added if the
ratio has to be 2:1?
14
Answer: Number of litres of sugar solution in the mixture = [1/(1+2) ] *45 = 15
litres.
So, 45-15 = 30 litres of salt solution is present in it.
Let the quantity of sugar solution to be added be x litres.
Setting up the proportion, sugar solution/salt
solution=(15+x)/30=2/1→x= 45.
Therefore, 45 litres of sugar solution has to be added to bring it to the ratio 2:1.
Question 2: A certain recipe calls for 3kgs of sugar for every 6 kgs of
flour. If 60kgs of this sweet has to be prepared, how much
sugar is required?
Solution:
Let the quantity of sugar required be x kgs.
3 kgs of sugar added to 6 kgs of flour constitutes a total of
9 kgs of sweet.
3 kgs of sugar is present in 9 kgs of sweet. We need to find
the quantity of sugar required for 60 kgs of sweet. So the
proportion looks like this.
3/9 = x/60 → x=20.
Therefore, 20 kgs of sugar is required for 60 kgs of sweet.
