Conversion formula just how to transform 48 hours to days?

We understand (by definition) that:1⁢hr≈0.041666667⁢d

We can set up a proportion to fix for the number of days.

You are watching: How many days are in 48 hours


Now, we cross main point to fix for ours unknown x:




Conversion in the contrary direction

The train station of the conversion element is the 1 job is same to 0.5 times 48 hours.

It can also be to express as: 48 hours is equal to 1 0.5 days.


An almost right numerical result would be: forty-eight hrs is around zero days, or alternatively, a day is about zero time forty-eight hours.

Units involved

This is how the systems in this conversion are defined:


"Midnight (or noon) on a 12-hour analog clock one hour is a unit of time conventionally reckoned together 1⁄24 that a day and also scientifically reckoned as 3,599–3,601 seconds, relying on conditions.The seasonal, temporal, or unequal hour was established in the ancient Near eastern as 1⁄12 of the night or daytime. Such hrs varied by season, latitude, and weather. It was subsequently split into 60 minutes, every of 60 seconds. That East asian equivalent to be the shi, which was 1⁄12 the the evident solar day; a similar system to be eventually developed in Europe i m sorry measured its same or equinoctial hour together 1⁄24 of together days measured native noon come noon. The minor variations the this unit were eventually smoothed by making the 1⁄24 the the mean solar day, based on the measure of the suns transit along the celestial equator fairly than follow me the ecliptic. This was ultimately abandoned due to the young slowing brought about by the Earths tidal deceleration through the Moon.In the modern-day metric system, hrs are an embraced unit that time same to 3,600 seconds yet an hour of Coordinated global Time (UTC) might incorporate a optimistic or an unfavorable leap second, make it critical 3,599 or 3,601 seconds, in bespeak to keep it within 0.9 seconds of global time, i beg your pardon is based on measurements the the median solar day in ~ 0° longitude."

"A work is a unit that time. In usual usage, the is one of two people an interval same to 24 hrs or daytime, the consecutive duration of time throughout which the sun is above the horizon. The period of time throughout which the earth completes one rotation with respect to the sun is called a solar day. Several definitions of this universal human concept are offered according to context, need and convenience. In 1960, the 2nd was redefined in terms of the orbital activity of the Earth, and was designated the SI base unit that time. The unit of measurement day, redefined in 1960 as 86 400 SI seconds and symbolized d, is not an SI unit, but is welcomed for use v SI. A polite day is generally 86 400 seconds, plus or minus a possible leap second in Coordinated global Time (UTC), and also occasionally to add or minus an hour in those places that adjust from or come daylight conserving time."
