If a fishbowl is placed in front of a sunny window the temperature will rise depending on how much thermal energy and radiant light is outside and making its way in through the window.
Extensive property (like volume and mass), can be measured.
The units are nm (nano-meter), km (kilo-meter), pm (pico-meter), dm (decimeter), mm (millimeter), m (meter), cm (centimeter), hm (hectometer) and gm (gigameter). Now we can express each of these units in terms of m.
1 nm = 
, 1 Km = 
1 pm = 
, 1 dm = 0.1 m, 1 mm = 0.001 m, 1 cm = 0.01 m, 1 hm = 100 m, 1 gm = 
. Thus the decreasing unit will be
gm>km>hm>m>dm>cm>mm>nm>pm
