Convert hyls to kilograms

Explanation

From this page you can convert hyls to kilograms (or kgf s²/m to kg) simply, by using the application above.

In case you are wondering, to convert from hyls to kilograms you need to multiply by 9.8067. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 kgf s²/m≈9.8067 kg

dimension	mass
symbol	kgf s²/m, mug
synonyms	kilogram-force second squared per meter, TME, metric slug

The hyl (kgf s²/m, mug) is a deprecated unit of mass of the gravitational metric system.

The hyl is also known as the metric slug or TEM.

Definition of the hyl

One hyl is equal to a mass that is accelerated by 1 m/s² when a force of one kilogram-force is exerted on it.

Value

One hyl is equal to 9.80665 kilograms.

The kilogram (kg) is the base unit of mass in the International System of Units.

Definition of the kilogram

It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 x 10^–34 when expressed in the unit J s, which is equal to kg m² s^–1, where the metre and the second are defined in terms of c and ∆ν_Cs.

Definition from the BIPM: Unit of mass

History

The first definition of the kilogram was "the mass of a liter of water". But this proved impractical and in 1889, the International Prototype Kilogram, a cylinder of platinum-iridium alloy, was made to serve as the reference.

In 1949 the mass of the IPK was found to be deverging from its copies. So, in order to ensure the stability of the unit, a new definition was devised based on the Planck constant and on 20 May 2019 this new definition came into effect.

Equivalences

One kilogram is equivalent to:

Some Facts

With an average of 1.4 kg (3 lbs), ostrich eggs are huge, yet, they are the smallest eggs relative to the size of the adult bird.

Prefix

10³

The prefix kilo- comes from the ancient Greek chilioi meaning thousand. The associated multiplicative factor is 1000 or 10³.

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.
