-7 SI UNITS-

-as of [9 APRIL 2024]

.

[the international system of quantities (ISQ) is a system based on 7 ‘base quantities’…]

*METER*
(“space”)
(“meeter”)

.

*SECOND*
(“time”)

.

*(KILO)-GRAM*
(“mass”)

.

*AMPERE*
(“electric charge”)

.

*KELVIN*
(“temperature”)

.

*MOLE*
(“amount”)

.

*CANDELA*
(“brightness”)

.

#1

*”THE METER”*
(length)
(3 space dimensions)

*the distance traveled by ‘light’ in a ‘vacuum’ in a specific fraction (‘1 / 299,792,458′) of a ‘second’)

*~ 1 / 300 millionth of a ‘second’*

*DEFINE ‘SPEED OF LIGHT’*
(constant)

*DEFINE ‘SECOND’*
(derived unit)

.

.

#2

*”THE SECOND”*
(‘time’)
(the ‘4th dimension’)

*the duration of 9,192,631,770 periods of the ‘radiation’ corresponding to the transition between the 2 hyper-fine levels of the ground state of the “caesium 133” atom*

(first you must build all the equipment necessary to measure)

*HERTZ*
(standard unit of ‘frequency’)
(1 ‘cycle’ per ‘second’)

.

.

#3

‘THE (KILO)GRAM”
(‘mass’)
(‘gravitational effects’)

*DEFINE “PLANCK’S CONSTANT”*

(planck’s constant in ‘joule seconds’)

(a ‘joule’ is amount of energy associated with an object when a force of ‘1 newton’ is applied over 1 meter)

“newton” =    1 kg⋅m⋅s−2

(so…)

“joule” = kg⋅m2⋅s−2

.

.

#4

“THE AMPERE”
(speed of ‘electric current’)

(measured in “coulombs per second”)

*DEFINE ‘ELEMENTARY CHARGE’*

(based on ‘elementary charge’ of 1 / -1)

.

.

#5

*”THE KELVIN”*
‘thermo-dynamic temperature’

*DEFINE ‘BOLTZMANN CONSTANT’*

.

.

#6

*”THE MOLE”*
‘amount of substance’

*DEFINE ‘AVOGADRO CONSTANT’*

.

.

#7

*”THE CANDELA”*
‘luminous intensity’

.

.

*SI-DERIVED UNITS*

.

*NON-SI-DERIVED UNITS*
