By calculation (generator: ["second_parameter@trueknowledge.com"]) I know that:

meter per second is the second parameter of 299, 792, 458 meters per second (the speed of light)

meter per second is the second parameter of 299, 792, 458 meters per second (the speed of light)

I know from locally stored knowledge that:

miles per hour is the optimum conversion unit for meter per second ([fact: ["1695066154@trueknowledge.com"]])

miles per hour is the optimum conversion unit for meter per second ([fact: ["1695066154@trueknowledge.com"]])

Fact 2:
1.609344
is the multiplier that converts
miles per hour and kilometer per hour
([fact: ["135583524@trueknowledge.com"]])

Fact 2
is true for
all time
([fact: ["1050411410@trueknowledge.com"]])

Fact 2
is true for
the beginning of time onwards
([fact: ["135583525@trueknowledge.com"]])

By calculation (generator: ["tpintersect@trueknowledge.com"]) I know that:

all time is the timeperiod intersection of all time and all time

all time is the timeperiod intersection of all time and all time

By calculation (generator: ["product@trueknowledge.com"]) I know that:

3.6 is the product of 2.2369362920544 and 1.609344

3.6 is the product of 2.2369362920544 and 1.609344

By calculation (generator: ["multiplier_that_converts2@trueknowledge.com"]) I know that:

Fact 3: 3.6 is the multiplier that converts meter per second and kilometer per hour

Fact 3: 3.6 is the multiplier that converts meter per second and kilometer per hour

Fact 3
is true for
all time

By calculation (generator: ["timeperiodtopoint@trueknowledge.com"]) I know that:

Fact 3 is true at July 31st 2014, 11:30:15

Fact 3 is true for the beginning of time onwards

Fact 3 is true for the beginning of time onwards

By calculation (generator: ["tpintersect@trueknowledge.com"]) I know that:

the beginning of time onwards is the timeperiod intersection of all time and the beginning of time onwards

the beginning of time onwards is the timeperiod intersection of all time and the beginning of time onwards

By calculation (generator: ["first_parameter@trueknowledge.com"]) I know that:

299,792,458 is the first parameter of 299, 792, 458 meters per second (the speed of light)

299,792,458 is the first parameter of 299, 792, 458 meters per second (the speed of light)

By calculation (generator: ["product@trueknowledge.com"]) I know that:

1,079,252,848.8 is the product of 3.6 and 299,792,458

1,079,252,848.8 is the product of 3.6 and 299,792,458

By calculation (generator: ["class_parametered_object@trueknowledge.com"]) I know that:

speed is the class of the parametered object 299, 792, 458 meters per second (the speed of light)

speed is the class of the parametered object 299, 792, 458 meters per second (the speed of light)

By calculation (generator: ["parametered_object_corresponding_to@trueknowledge.com"]) I know that:

1,079,252,848.8 kilometers per hour is the parametered object corresponding to speed and 1,079,252,848.8 and kilometer per hour

1,079,252,848.8 kilometers per hour is the parametered object corresponding to speed and 1,079,252,848.8 and kilometer per hour

By calculation (generator: ["equivalent_to6@trueknowledge.com"]) I know that:

Fact 4: 1,079,252,848.8 kilometers per hour is equivalent to 299, 792, 458 meters per second (the speed of light)

Fact 4: 1,079,252,848.8 kilometers per hour is equivalent to 299, 792, 458 meters per second (the speed of light)

Fact 4
is true at
July 31st 2014, 11:30:15

Fact 4:
kilometer per hour
is the unit used in
1,079,252,848.8 kilometers per hour

I used the following facts to provide this answer:

299, 792, 458 meters per second (the speed of light) has always been the top speed of light

miles per hour is the optimum conversion unit for meter per second

1.609344 has always been the multiplier that converts miles per hour and kilometer per hour and will be forever

1.609344 has always been the multiplier that converts miles per hour and kilometer per hour
