Metric units: Convert microns (micrometres) to millimetres. One thousand microns (μm) is equal to how many millimetres (mm)? Choose the correct option.

Q: Metric units: Convert microns (micrometres) to millimetres. One thousand microns (μm) is equal to how many millimetres (mm)? Choose the correct option.

Given data 1 μm = 10-6 m. 1 mm = 10-3 m. Calculation 1000 μm = 1000 × 10-6 m = 10-3 m = 1 mm. Final Answer 1 millimetre

Difficulty: Easy

1 millimetre
0.1 millimetre
10 millimetres
0.01 millimetre

Correct Answer: 1 millimetre

Explanation:

Given data

1 μm = 10^-6 m.
1 mm = 10^-3 m.

Calculation
1000 μm = 1000 × 10^-6 m = 10^-3 m = 1 mm.

Final Answer
1 millimetre
