FILL POWER MEASURING UNITS
Several units of measure are used for Fill (or Loft) Power of down and feathers.
- USA
- Cubic inches per ounce (cu in / oz)
- International / European / JIS
- Height in millimeters per 30 grams (mm / 30g)
- Scandanavia / New Europe
- Height in millimeters per 20 grams (mm / 20g)
- European (Alternate)
- Liters per Kilogram (L / kg)
- European (Alternate)
- Cubic centimeters per 30 grams (cm^3 / 30g)
- European (proposed volume)
- Cubic centimeters per gram (cm^3 / g)
Conversion from CUBIC INCHES / OZ to other measurements.

Example of Calculation from cubic inches |
| Value x | 0.252 = | mm / 30g | 550 x .252 = 139 mm / 30g |
| Value x | 0.017 = | cm / 20g | 550 x .017 = 9.35 cm / 20g |
| Value x | 0.546 = | liter / kg | 550 x .546 = 300 liter / kg |
| Value x | 16.38 = | cm^3 / 30g | 550 x 16.38 = 9009 cm^3 / 30g |
| Value x | 0.546 = | cm^3 / g | 550 x .546 = 300 cm^3 / g |
