Convert 4 feet 3 inches to cm

Formulas:

The formula to convert length from feet to centimeters is:

Length_{(centimeters)} = Length_(feet) / 0.032808398950000005 ——①

The formula to convert length from inches to centimeters is:

Length_{(centimeters)} = Length_(inches) / 0.3937007874 ——②

Problem at hand:

We need to convert given length of 4 feet to centimeters, and 3 inches to centimeters, and finally add the two resulting values.

Given:

The given length value is

Length_(Feet) = 4

Length_(Inches) = 3

Substitution:

Substitute Length_(feet) = 4 in the conversion formula ①.

Length_{(centimeters)} = Length_(feet) / 0.032808398950000005

Length_{(centimeters)} = 4 / 0.032808398950000005

Length_{(Centimeters)} = 121.92 ——③

Substitute Length_(inches) = 3 in the conversion formula ②.

Length_{(centimeters)} = Length_(inches) / 0.3937007874

Length_{(centimeters)} = 3 / 0.3937007874

Length_{(Centimeters)} = 7.62 ——④

Simplification:

Add the two values obtained in steps ③ and ④.

Length_{(Centimeters)} = 121.92 (from feet) + 7.62 (from inches)

Length_{(Centimeters)} = 129.54

Conclusion:

Therefore, given length of 4 feet 3 inches is equal to 129.54 cm.
