<span>REM sleep is a period of sleep where your eyes move rapidly (Rapid Eye Movement). After a period of REM sleep, your body experiences 5 to 15 minute periods of non-REM sleep. During this lighter sleep it is much easier for you to be awakened. There are different periods of REM sleep which can last from 10 minutes to one hour. The longer you sleep, the longer the REM period will last. This cycle will occur on average every 90 minutes.</span>

1) 35mL to L    1 L = 1000ml  so, 35mL = 35÷1000=0.035L

2) 950gm =  1Kg =1000g SO, 950÷1000= 0.950 Kg

3) 275mm to cm=   1mm= 1÷10 cm  so, 275÷10= 27.5cm

4)1000mL to L = 1L=1000ml so, it will equal to 1L

5)4500mg to g = 1mg= 1÷1000g  so, it will equal to 4.5g

6)25cm to mm   = 1cm= 10mm  so, 25X 10= 250mm

7)0.005Kg to mg,   so 1Kg= 10∧6 mg   so, 0.005X10∧6= 5000mg

8)0.075m to cm,  so 1m =100cm  so, 0.075X100= 0.75cm

9)15 g to mg , so 1g = 1000mg   so, 15X1000= 15000mg
