Ubadilishaji wa Kawaida wa Masi katika Uhandisi

From → To	Multiply by	Mfano
kg → lb	2.20462	100 kg = 220.46 lb
lb → kg	0.45359	100 lb = 45.36 kg
oz → g	28.3495	1 oz = 28.35 g
g → oz	0.03527	100 g = 3.53 oz
tani → short ton	1.10231	1 t = 1.102 short tons
short ton → tani	0.90718	1 ST = 0.907 t
stone → kg	6.35029	10 stone = 63.5 kg

Vidokezo vya Kukariri kwa Urahisi

• 1 kg ≈ 2.2 lb (kwa makadirio ya haraka)
• 1 lb ≈ 454 g
• 1 aunsi ≈ 28.35 g
• 1 stone = 14 lb = 6.35 kg (used in UK for body weight)
• 1 tonne = 1000 kg ≈ 2205 lb
• 1 short ton (US) = 2000 lb ≈ 907 kg
• 1 long ton (UK) = 2240 lb ≈ 1016 kg
• 1 grain ≈ 64.8 mg (inatumika katika balistiki na dawa)

Mass vs Weight

Katika matumizi ya kila siku, “uzito” na “masi” hutumika kwa kubadilishana, lakini zina tofauti:

• Mass (kg, lb-mass) ni kiasi cha jambo — kinabaki sawa kila mahali
• Weight (N, lbf) ni nguvu ya uvutano wa ardhini — hutofautiana kulingana na mahali
• On Earth’s surface: Weight (N) = Mass (kg) × 9.81 m/s²
• Masi ya kg 100 ina uzito wa N 981 duniani lakini N 163 tu mwezini

Vitengo Maalum kwa Matumizi

• Balancing: Unbalance measured in g·mm (grams × millimeters) or oz·in (ounces × inches)
• Pharmacy: Grains (1 gr = 64.8 mg), drams, scruples
• Metali za thamani: Troy ounce (31.103 g) ≠ Avoirdupois ounce (28.350 g)
• Gemstones: Karati (1 ct = 0.2 g)
