Poundal

Poundal

Das poundal, kurz pdl, ist eine nicht SI-konforme Einheit der Kraft. Es ist ein Teil des absoluten foot-pound-second angloamerikanischen Maßsystems, eines kohärenten Untersystems der englischen Einheiten, das im Jahre 1879 eingeführt wurde.

Es ist definiert als 1 Poundal = 1 pdl. = 1 lb·ft·s-2 (lb=Pound, ft=Foot, s=Sekunde). Es ist 1 pdl. = 0,138 254 954 376 Newton (N)

Newton Dyn Kilopond Pound-force Poundal
1 N ≡ 1 kg·m/s² = 105 dyn ≈ 0,102 kp ≈ 0,225 lbf ≈ 7,233 pdl
1 dyn = 10−5 N ≡ 1 g·cm/s² = 1/980665 kp ≈ 1/444822 lbf ≈ 1/13825,5 pdl
1 kp = 9,80665 N = 980665 dyn ≡ gN · 1 kg ≈ 2,205 lbf ≈ 70,932 pdl
1 lbf = 4,4482216152605 N ≈ 444822 dyn = 0,45359237 kp ≡ gN · 1 lb ≈ 32,174 pdl
1 pdl = 0,138254954376 N ≈ 13825,5 dyn ≈ 0,0141 kp ≈ 0,0311 lbf ≡ 1 lb·ft/s²

Newton ist die SI-Einheit der Kraft. Nicht aufgelistet sind zusammengesetzte Einheiten.
