Armando
stepped on the scale in his doctor’s office and found out that his mass is 35
kg. What is his mass in grams?
1.
List the given and unknown values.
Given: mass in kilograms_35 kg
Unknown: mass
in grams_? g
2.
Determine the relationship between units.
By using the table below, you know that you will
multiply because it takes a lot of grams to make up each kilogram.
3.
Write the equation for the conversion.
mass
in g = mass
in kg x 1000 g
1 kg
4.
Insert the known values into the equation, and solve.
mass
in g = 35 kg x 1000 g
1 kg
mass
in g = 35 000 g

1.
List the given and unknown values.
Given: height in meters =
553 m
Unknown: height
in kilometers_? km
2.
Determine the relationship between units.
Using the table above, you can see that you will
divide because there are fewer kilometers than meters in a given distance.
3.
Write the equation for the conversion.
height
in km = height
in m x 1 km
1000 m
4.
Insert the known values into the equation, and solve.
height
in km = 553 m x 1
km
1000 m
height
in km = 0.553 km
