1″ inch = 8 soot
1 fit = 12″ inch
1 miter = 3 fit 3 inch 3 soot
1 centimeter = 10 mm
100 centimeter = 1 meter
1000 mm = 1 meter
1 meter = 39 inch 3 soot
Pipe OD formula
12″ inch after use the formula inch × 25.4 = pipe OD
14″× 25.4 = 355.6 mm pipe OD
Pipe CF formula
Pipe OD × 3.142 = pipe CF mm
4″ Pipe OD 114.30 × 3.142 = pipe CF 4″ 359.1
pipe I D formula
Pipe OD mince thickness × 2 = pipe I D
14″ Pipe thickness 8 mm
14″ pipe do 355.6 – 16 mm = 339.6 mm I D
Elbow center formula
LR 90° degree inch × 38.1 = elbow center
10″ × 38.1 = 381 mm elbow center
LR 45° degree inch × 15.7 mm 90° = elbow center
10″ × 15.7 = 157 mm 45° elbow center
CF × degree ÷ 360 × 2 × cut = answer
Answer × 6 = middle piece Answer
Answer ÷ 2 = side piece
