Julian Century Solution

Follow our step by step solution on how to calculate Julian Century?

FIRST Step Consider the formula

JC = \frac{JD - JD ref}{t ref}

Next Step Substitute values of Variables

∴

JC = \frac{427d - 7d}{1.4}

Next Step Convert Units

∴

JC = \frac{3.7E+7s - 604800s}{1.4}

Next Step Prepare to Evaluate

∴

JC = \frac{3.7E+7 - 604800}{1.4}

Next Step Evaluate

∴

JC = 25920000s

LAST Step Convert to Output's Unit

∴

JC = 300d
