There are 60 minutes in an hour. This is the simple, man-made concept to keep in mind when calculating minutes as a fraction of an hour. The best way to understand the calculation of minutes as fractions of an hour is to first visualize some common hour-fractions which we see every day.
Visualizing the Fraction
Visualize the face of a clock as a pie, seeing the quarters that mark 15 minutes, 30 minutes, 45 minutes, and 60 minutes in your mind's eye. When you imagine the 15 minute mark, what do you see? It is a quarter (or 1/4) of a pie! Thus, 15 minutes equate to 1/4 hour. Now, if you further halved the quarter pie, what would you get? Yes, one-eighth of a pie. Thus, seven-and-a-half minutes equate to one-eighth (1/8) of an hour.

How to Convert From Acreage to Square Feet
Originally, an acre was simply the amount of land one man could plow in a day with one ox. Modern-day machinery has made that definition obsolete, and governments have standardized the size. In land surveying, lot and parcel sizes typically are described in terms of acres. For smaller residential lots, it might be more beneficial to measure in terms of square feet instead, which can be determined by a simple calculation.
1. Determine the number of acres you need to convert into square feet.
2. Convert into decimal form the amount of acres you want to convert to square feet using the calculator or pencil and paper. For example, if you need to convert 2 1/2 acres into square feet, convert it to 2.5 acres.
3. Multiply the number of square feet in 1 acre, which is 43,560 square...

How to Calculate Training Man Days
Training employees is a useful business management paradigm which helps optimize employee productivity by giving fresh insight, new skills or an opportunity to hone existing skills. Many companies mandate employee participation in a set number of "man days" of training every month or year. Other businesses mandate a certain number of man days be spent over the entirety of their company without stipulating any individual's participation. Knowing how to calculate man hours allows you to effectively address these training requirements.
Calculating Individual Man Days
1. Decide what constitutes a "man day." In most cases, a "man day" is eight hours, although that is up to a company to decide. A company may decide that a two-hour lecture counts as half a day or a quarter of a...

How to Calculate Man-Hours and Lost Productivity
Productivity is a company's output per unit of labor input. Man-hours measure labor input. It is the number of employees multiplied by the number of hours worked. Businesses may lose productivity due to several reasons, including equipment downtime and malfunction, information technology failures and employee sick days. Lost productivity leads to higher costs and lower profits. Calculate the cost of lost productivity to understand how and where to improve operating efficiencies.
1. Tabulate the average monthly man-hours of lost productivity by job classification. Keep a record of the number of hours lost on a monthly or even a daily basis due to scheduled maintenance downtime, recovery of IT failures or loss of data, and other reasons. Track the number of hours lost due...

How to Calculate Man-Hour Cost
On flat-rate projects, the cost of labor and materials can diminish your profit margin. By predicting how many hours it will take to complete the project and how many workers to hire, you can create a more-accurate quote for the client. Whether you pay your workers on contract or by the hour, calculating the man-hour costs before hiring contract workers for a project will provide you with a better idea of how much to pay.
1. Find the total number of hours worked by multiplying the number of working hours in a day by the number of total working days. For example, if your men worked 20 days for eight hours a day, the total number of hours would be 160 hours (20 x 8 = 160).
2. Multiply the total number of hours by the number of workers to find the total man-hours. For example,...
