Which of the following is not equal to 1 mm?
1 mm means 1 millimeter, where milli stands for 10-3.
Answer: Only option a) i.e. 100 cm is not equivalent to 1mm.
Go through the explanation to understand the steps to the solution.
a) 100 cm
b) 1/10 cm
c) 1/1000 m
d) 1/1000000 km
Using unit conversion table for length, we see that:
1mm = 10 cm
Thus, option (A) is not correct.
1cm = 10 mm. Thus, 1mm = 1/10 cm
Hence, option (B) is correct
1m = 1000 mm. Thus, 1mm = 1/1000 m
Hence, option (C) is correct.
1km = 1000 m = 100000 cm = 1000000 mm. Thus, 1mm = 1/1000000 km
Hence, option (D) is correct.
