Question

1. 550 mm = ? m
2. 3.5 s (seconds) = ? ms (milliseconds)
3. 1.6 kg = ? g
4. 2500 mg = ? kg
5. 4 cm = ? mm (micrometers)
6. 2800 millimoles = ? moles
7. 6.1 amps = ? milliamps
8. 3 micrograms = ? nanograms
9. 50 dg = ? g
10. 5 km = ? m

Explanation:

1. $550\ \text{mm} =?\ \text{m}$

Step1: Recall unit conversion (1 m = 1000 mm)

To convert millimeters to meters, divide by 1000.
$550\ \text{mm} = \frac{550}{1000}\ \text{m}$

Step2: Simplify the fraction

$\frac{550}{1000} = 0.55$

Step1: Recall unit conversion (1 s = 1000 ms)

To convert seconds to milliseconds, multiply by 1000.
$3.5\ \text{s} = 3.5\times1000\ \text{ms}$

Step2: Calculate the product

$3.5\times1000 = 3500$

Step1: Recall unit conversion (1 kg = 1000 g)

To convert kilograms to grams, multiply by 1000.
$1.6\ \text{kg} = 1.6\times1000\ \text{g}$

Step2: Calculate the product

$1.6\times1000 = 1600$

Answer:

$0.55\ \text{m}$

2. $3.5\ \text{s} =?\ \text{ms}$
