1 Feet + 30 CM Combined Length
Understanding Combined Measurements:
When you have 1 foot plus 30 cm, you're combining imperial and metric units. Here's how to calculate the total:
Step 1: Convert feet to cm
1 foot = 30.48 cm
Step 2: Add the cm values
30.48 cm + 30 cm = 60.48 cm
Step 3: Convert back to feet
60.48 ÷ 30.48 = 1.984 feet
= 1 foot 11.81 inches
Result: 1 foot + 30 cm = 60.48 cm = 1.984 feet = 1' 11.81"
