No.

Mass in kg can be converted to lb by multiplying mass in kg by #2.205"lb/kg"#.

Example

On a three-year-old child's birthday, she has a mass of #"15.9 kg"#. On her next birthday, she has a mass of #"20.4kg"#.

Determine her weight on both birthdays.

Third birthday

#15.9cancel"kg"xx(2.205"lb")/(1cancel"kg")="35.1 lb"#

Forth birthday

#20.4cancel"kg"xx(2.205"lb")/(1cancel"kg")="45.0 lb"#
