To convert millimeters to meters, we can use the conversion factor where 1 meter is equal to 1000 millimeters. So, to convert 1450 mm to meters, we divide the number of millimeters by 1000:
Calculation:
1450 mm ÷ 1000 = 1.450 m
Now, to express 1.450 meters with the correct number of significant digits, we need to look at the original measurement, which is 1450 mm. This number is typically understood to have four significant figures because of the trailing zeros after the ‘4’. To maintain this level of precision, we keep the ‘1.450’ as is, which means our final answer is:
1.450 meters
