  2. Federal Bridge Gross Weight Formula - Wikipedia

    Others, such as Massachusetts, impose a less complicated fine schedule whereby a vehicle that violates the limits by less than 10,000 pounds (4,500 kg) is fined $40 per 1,000 pounds (450 kg), while a violation over 10,000 pounds (4,500 kg) pays $80 per 1,000 pounds (450 kg) (e.g. 5,000 pounds or 2,300 kilograms overweight equals a $200 fine).

  3. Thrust-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Thrust-to-weight_ratio

    The weight (N) is calculated by multiplying the mass in kilograms (kg) by the acceleration due to gravity (m/s 2). The thrust can also be measured in pound-force (lbf), provided the weight is measured in pounds (lb).

    For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...

    kilogram (kg), the standard SI unit of mass. tonne (t), a non- SI but an accepted metric unit, defined as 1,000 kilograms . " short ton " is used in the US; 1 short ton = 2,000 pounds = 0.907 tonnes.

  6. Specific impulse - Wikipedia

    en.wikipedia.org/wiki/Specific_impulse

    If mass is used, specific impulse is an impulse per unit of mass, which dimensional analysis shows to be equivalent to units of speed; this interpretation is commonly labeled the effective exhaust velocity. If a force-based unit system is used, impulse is divided by propellant weight (weight is a measure of force), resulting in units of time.

  7. Power-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Power-to-weight_ratio

    A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.

    Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.

  9. Dimensional weight - Wikipedia

    The 35.1 pounds is the 'theoretical" weight of the package if it had a density of 166 in 3 /lb or 10.4 lb/ft 3: (18 × 18 × 18) = 3.375 ft 3 × 10.4 lb/ft 3 = 35.1 lb. Note that for the USPS there are two different calculations for DIM weight: (L × W × H)/194 for domestic shipments and (L × W × H)/166 for international shipments.
