CONVERTING POUNDS TO KILOGRAMS STEP OUTLINE VIEW
For example, the client’s weight is 128 lb. Determine this client’s weight in kg.
(Round to the tenth.)

STEP 1: What is the unit of measurement you need to
calculate? kg

STEP 2: Set up an equation and solve for X, with X representing the amount of
kilograms.




Cross multiply and solve for
X. X = 58.1818

STEP 3: Round if necessary, using general rounding rules.
You should also follow policies and procedures of your facility. For the purpose of
this module, we will round to the tenth. Therefore, 58.1818 rounds to 58.2.


STEP 4: Reassess to determine if the equivalent makes sense.
If 1 kg = 2.2 lb, it makes sense that 128 lb = 58.2 kg.

For example, the client’s weight is 96 lb. Determine this client’s weight in kg.
(Round to the tenth.)

STEP 1: What is the unit of measurement you need to
calculate? kg

STEP 2: Set up an equation and solve for X, with X representing the amount of
kilograms.




Cross multiply to solve for X.
X = 43.6363

STEP 3: Round if necessary, using general rounding rules. You should also follow
policies and procedures of your facility.
For the purpose of this module, we will round to the tenth. Therefore, 43.6363
rounds to 43.6.

,STEP 4: Reassess to determine if the equivalent makes sense.
If 1 kg = 2.2 lb, it makes sense that 128 lb = 43.6 kg.

For example, the client’s weight is 5 lb 4 oz. Determine this client’s weight in lb.
(Round to the tenth.)

STEP 1: What is the unit of measurement you need to
calculate? lb

STEP 2: Set up an equation and solve for X, with X representing the amount of




pounds.
Cross multiply to solve for X.
X = 0.25

STEP 3: Round if necessary, using general rounding rules. You should also follow
policies and procedures of your facility.
For the purpose of this module, we will round to the tenth. Therefore, 0.25
rounds to 0.3.


STEP 4: Reassess to determine if the equivalent makes sense.
If 1 lb = 16 oz, it makes sense that 4 oz = 0.3 lb.


STEP 5: Remember to add the remainder weight. It is important not to forget the
rest of the client’s weight, which in this example is 5 lb.
Therefore, 5 lb + 0.3 lb = 5.3 lb.

For example, the client’s weight is 21 lb 14 oz. Determine this client’s weight in
pounds. (Round to the tenth.)

STEP 1: What is the unit of measurement you need to calculate?
lb

STEP 2: Set up an equation and solve for X, with X representing the amount of lb.




Cross multiply to solve for X.

, X = 0.875

STEP 3: Round if necessary, using general rounding rules. You should also follow
policies and procedures of your facility. For the purpose of this module, we will round
to the tenth. Therefore, 0.875 rounds to 0.9.

STEP 4: Reassess to determine if the equivalent makes sense.
If 1 lb = 16 oz, it makes sense that 14 oz = 0.9 lb.

STEP 5: Remember to add the remainder weight. It is important not to forget the
rest of the client’s weight, which in this example is 21 lb. So 21 lb + 0.9 lb = 21.9
lb.

For example, convert a client’s weight from oz to lb, then from lb to kg. The client’s
weight is 65 lb 12 oz. (Round to the tenth.)

STEP 1: What is the unit of measurement you need to
calculate? lb

STEP 2: Set up an equation and solve for X, with X representing the amount of
pounds.




Cross multiply and solve for
X. X = 0.75.

STEP 3: Round if necessary, using general rounding rules. You should also follow
policies and procedures of your facility.
For the purpose of this module, we will round to the tenth. Therefore, 0.75
rounds to 0.8.


STEP 4: Reassess to determine if the equivalent makes sense.
If 1 lb = 16 oz, it makes sense that 12 oz = 0.8 lb.

STEP 5: Remember to add the remainder weight. It is important not to forget the
rest of the client’s weight, which in this example is 65 lb.
So 65 lb + 0.8 lb = 65.8 lb.

The client’s weight is 65.8 lb. Determine this client’s weight in kilograms. (Round to
the tenth.)

, STEP 6: What is the unit of measurement you need to
calculate? kg

STEP 7: Set up an equation and solve for X, with X representing the amount of
kilograms.




Cross multiply and solve for
X. X = 29.9

STEP 8: Round if necessary, using general rounding rules. You should also follow
policies and procedures of your facility.
For the purpose of this module, we will round to the tenth. In this example, there
is no reason to round your answer because it is already rounded to the tenth.

STEP 9: Reassess to determine if the equivalent makes sense.
If 1 kg = 2.2 lb, it makes sense that 65.8 lb = 29.9 kg.

For example, convert a client’s weight from oz to lb, then from lb to kg. The client’s
weight is 33 lb 8 oz. (Round to the tenth.)

STEP 1: What is the unit of measurement you need to
calculate? lb

STEP 2: Set up an equation and solve for X, with X representing the amount of
pounds.




Cross multiply and solve for
X. X = 0.5

STEP 3: Round if necessary, using general rounding rules. You should also follow
policies and procedures of your facility.
For the purpose of this module, we will round to the tenth. In this example, there
is no reason to round your answer because it is already rounded to the tenth.


STEP 4: Reassess to determine if the equivalent makes sense.
If 1 lb = 16 oz, it makes sense that 8 oz = 0.5 lb.
