metric conversions

1. convert the following within the metric system.

a) 60 g to kg
b) 2000 ml to l
c) 76.07 dm to mm
d) 0.45 s to ms

Explanation:

Step1: Recall metric - prefix conversion factors

1 kg = 1000 g, 1 L = 1000 mL, 1 dm = 100 mm, 1 s = 1000 ms.

Step2: Convert 60 g to kg

Use the conversion factor $1\ kg = 1000\ g$. So, $60\ g=\frac{60}{1000}\ kg = 0.06\ kg$.

Step3: Convert 2000 mL to L

Use the conversion factor $1\ L = 1000\ mL$. So, $2000\ mL=\frac{2000}{1000}\ L = 2\ L$.

Step4: Convert 76.07 dm to mm

Use the conversion factor $1\ dm = 100\ mm$. So, $76.07\ dm=76.07\times100\ mm = 7607\ mm$.

Step5: Convert 0.45 s to ms

Use the conversion factor $1\ s = 1000\ ms$. So, $0.45\ s=0.45\times1000\ ms = 450\ ms$.

Answer:

a) 0.06 kg
b) 2 L
c) 7607 mm
d) 450 ms
