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
