It's the same. 100 cm is the same as 1 m. Centi means "1/100".
The centi- prefix (c) means 1/100→ 1 cm = 1/100 m = 0.01 m→ 100 cm = 100 × 1/100 m = 1 mConvert to the same units then do the addition, either:convert to cm:1.6 m = 1.6 × 100 cm = 160 cm → 1.6 m + 11 cm = 160 cm + 11 cm = 171 cmconvert to m:11 cm = 11 × 0.01 m = 0.11 m → 1.6 m + 11 cm = 1.6 m + 0.11 m = 1.71 mUse the conversion which is easier to work with or is the required units of the answer.
To compare 600 cm and 5 m, we need to convert both measurements to the same unit. Since 1 m is equal to 100 cm, 5 m is equal to 500 cm. Therefore, 600 cm is indeed greater than 5 m when comparing both measurements in centimeters.
There are 100 centimeters in a meter, so if you have 45 cm, it's the same as 0.45 m. Likewise, if you have 2.348 m, you have 234.8 cm.
1 m = 100 cm 1 m² = 1 m × 1 m = 100 cm × 100 cm = 10,000 cm²
