Related units include the picul, equal to 100 catties, and the tael, which is 1 ⁄ 16 of a catty. A stone is a former unit used in Hong Kong equal to 120 catties and a gwan ( 鈞 ) is 30 catties. Catty or kati is still used in Southeast Asia as a unit of measurement in some contexts especially by the significant Overseas Chinese populations ...
A picul / ˈ p ɪ k əl /, [1] dan [2] or tam, [3] is a traditional Asian unit of weight, defined as "as much as a man can carry on a shoulder-pole". [1] Historically, it was defined as equivalent to 100 or 120 catties, depending on time and region. The picul is most commonly used in southern China and Maritime Southeast Asia.
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
The propellant mass fraction is the ratio of just the propellant to the entire mass of the vehicle at takeoff (propellant plus dry mass). In the cases of a single-stage-to-orbit (SSTO) vehicle or suborbital vehicle, the mass fraction equals the propellant mass fraction, which is simply the fuel mass divided by the mass of the full spaceship.

Bird flu has been on the rise in Washington state and one sanctuary was hit hard: 20 big cats – more than half of the facility’s population – died over the course of weeks.
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.
