IV. Conversion of the metric-British system

1. Conversion Formula of Number and British Branches

Tex = 590.5/Ne or tex = 583.1/Ne

2. The Conversion Formula of Number and Metric Support

Tex = 1000/Nm

3. Conversion Formula of Number Number and Daniel Number

Tex = D/9 4 Conversion of Common Measurement Units

4.1 Unit of Length

Metric system: meter (m), centimeter (cm), millimeter (mm). LM = 100cm = 1000mm

British system: yard (yd), inch (in). One yard = 3 feet, one foot = 12 inches.

Conversion: 1 yard = 0.9144 meters, 1 foot = 0.3048 meters, 1 inch = 2.54 cm = 25.4 mm.

One meter = 1.0936 yards = 3.2808 feet.

4.2 mass (weight) units

Metric system: tons (t), kilograms (kg), grams (g). 1 ton = 1000 kg, 1 kg = 1000 g, 1 g = 1000 mg.

British system: lb, Oz and gr. One pound = 16 ounces = 7000 green and one ounce = 437.5 green.

Conversion: 1 pound = 0.4536 kg = 453.6 g, 1 ounce = 28.35 g, 1 Green = 0.0648 G.

1 kilogram = 2.2046 pounds, 1 gram = 15.432 green.

4.3 area units

Metric system: 2 meters (m2), 2 centimeters (cm2), 2 millimeters (mm2). 1 cm 2 = 10 000 cm 2, 1 cm 2 = 100 mm 2.

British system: code 2 (yd2).

Conversion: 1 m 2 = 1.196 code 2

4.4 units of force

Metric system: Newton (N), Li Newton (cN). 1 Newton (N) = 100 centimeter Newton (cN), 1 kilogram force (kgf) = 1000 grams force (gf).

British system: lbf.

Conversion: 1 kilogram force (kgf) = 9.807 Newton (N), 1 gram force (gf) = 0.9807 centimeter Newton (cN),

1 Newton (N) = 0.225 lbf.

4.5 Volume Unit

Metric system: 3 meters, 3 liters, 3 milliliters. 1 metre 3 = 1000 liters, 1 liter = 1000 milliliters 3.

British system: gallon, code 3.

Conversion: 1 meter 3 = 1.308 yards 3, 1 liter = 0.22 gallons, 1 gallon = 4.546 liters.

4.6 Plane Density Unit

Metric system: kg/m 2 (kg/m 2).

British system: oz/yd2.

Conversion: 1 kg/m 2 = 29.4535 ounces/yard 2. 4.7 Yarn count

Units: Tex, den, Ne and Nm.

Conversion: 1 Daniel (den) = Tex * 9, Ne = 590.5/Tex, British branch number.

Tex = 1000/ Metric Expenditure (Nm).

4.8 Fabric Density

Units: Metric density (root/10cm) and British density (root/in).

Conversion: Metric density (root/10cm) = British density (root/in) / 0.254.
