In August 2018, a Chinese research group announced new measurements based on torsion balances, 6.674 184 (78) × 10 −11 m 3 ⋅kg −1 ⋅s −2 and 6.674 484 (78) × 10 −11 m 3 ⋅kg −1 ⋅s −2 based on two different methods. [47] These are claimed as the most accurate measurements ever made, with standard uncertainties cited as low as ...
The current best estimate for the mass of Earth is M 🜨 = 5.9722 × 10 24 kg, with a relative uncertainty of 10 −4. [2] It is equivalent to an average density of 5515 kg/m 3. Using the nearest metric prefix, the Earth mass is approximately six ronnagrams, or 6.0 Rg. [3]
If the mass of an object is estimated as 3.78 ± 0.07 kg, so the actual mass is probably somewhere in the range 3.71 to 3.85 kg, and it is desired to report it with a single number, then 3.8 kg is the best number to report since its implied uncertainty ± 0.05 kg gives a mass range of 3.75 to 3.85 kg, which is close to the measurement range.
The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and Δν Cs. —
The kilogram-force (kgf or kg F), or kilopond (kp, from Latin: pondus, lit. 'weight'), is a non-standard gravitational metric unit of force . It is not accepted for use with the International System of Units (SI) [ 1 ] and is deprecated for most uses.
Kinetic energy per unit mass: 1 / 2 v 2, where v is the speed (giving J/kg when v is in m/s). See also kinetic energy per unit mass of projectiles . Potential energy with respect to gravity, close to Earth, per unit mass: gh , where g is the acceleration due to gravity ( standardized as ≈9.8 m/s 2 ) and h is the height above the ...
Human body weight is a person's mass or weight.. Strictly speaking, body weight is the measurement of mass without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital weighing scales.
