This all depends on a few factors (sorry there's really no straight answer here)
How thick is your thread? A delicate silk thread is a lot thinner than the thicker, tougher stuff used to stitch up leather...
What type of bobbins are you using? (a metal singer 15k bobbin will hold a more thread than a plastic type 66) both design type and material for construction affect the figure.
So like I said there is no straight answer here...
10
220 inches
22, 220 ÷ 10 = 22
400/2 = 200 40/2 = 20 200+20=220
220/22 = 10
220
136.7 mph is 220 kph.
220 yd = 0.201168 km
220 ml = 0.22 liters
220 meters = 120.3 fathoms
220 meters equals 22,000cm
220 cc of water is 220 ml.
