Convert the following units to their S.I units (i) 10g (ii)100mm(iii)250cm(v) 500mg and 20km
(i) 10g = 0.01 kg (since 1 kg = 1000 g)
(ii) 100mm = 0.1 m (since 1 m = 1000 mm)
(iii) 250cm = 2.5 m (since 1 m = 100 cm)
(iv) 500mg = 0.5 g (since 1 g = 1000 mg)
(v) 20km = 20000 m (since 1 km = 1000 m)
(i) 10g = 0.01 kg
To convert grams (g) to kilograms (kg), divide by 1000 (since 1 kilogram = 1000 grams). Therefore, 10g is equal to 0.01 kg in SI units.
(ii) 100mm = 0.1 meters
To convert millimeters (mm) to meters (m), divide by 1000 (since 1 meter = 1000 millimeters). Therefore, 100mm is equal to 0.1 meters in SI units.
(iii) 250cm = 2.5 meters
To convert centimeters (cm) to meters (m), divide by 100 (since 1 meter = 100 centimeters). Therefore, 250cm is equal to 2.5 meters in SI units.
(iv) 500mg = 0.5 grams
To convert milligrams (mg) to grams (g), divide by 1000 (since 1 gram = 1000 milligrams). Therefore, 500mg is equal to 0.5 grams in SI units.
(v) 20km = 20000 meters
To convert kilometers (km) to meters (m), multiply by 1000 (since 1 kilometer = 1000 meters). Therefore, 20km is equal to 20000 meters in SI units.
