1000mm = 1 m
100 cm = 1 m
10 mm = 1 cm
1 Km = 1000 m
60 Sec = 1 min
60 min= 1 hr
24 hr = 1 day
365 days = 1 year
1 days = 1 week
52 weeks = 1 year

Answer 1

To convert 12,345 mm into kilometers (km), we can use the metric conversion factors provided. Here are the steps:

1. Convert millimeters to meters: \[ 1000 \text{ mm} = 1 \text{ m} \] So, to convert 12,345 mm to meters: \[ \text{meters} = \frac{12,345 \text{ mm}}{1000} = 12.345 \text{ m} \]

2. Convert meters to kilometers: \[ 1 \text{ km} = 1000 \text{ m} \] Therefore, to convert 12.345 m to kilometers: \[ \text{kilometers} = \frac{12.345 \text{ m}}{1000} = 0.012345 \text{ km} \]

So, 12,345 mm is equal to 0.012345 kilometers.
