Time for Units

The Time for Units calculator computes the period of time (T) needed to produce or consume a certain number units based on the unit time to produce or consume a designated number of units.

INSTRUCTIONS: Choose units and enter the following:

• (X) Total Number of Units to be produced, consumed or processed. 
• (UN) Unit Number processed in Unit Period (e.g. 3,800 apples picked per week)
• (UP) Unit Period required to process the Unit Number of items (e.g. one week to pick 3,800 apples)

Time to Process Units (T): The calculator returns the required time for the production or consumption of the units.  Time is returned in hours.  However, this can be automatically converted to other time units (e.g. days or weeks) via the pull-down menu.

The Math / Science

Production and consumption of materials over time can be estimated or measured based on the average production or consumption rate of a unit.  This calculator uses a known unit production rate (e.g. 6 marbles in 20 seconds) to compute the total amount of time needed to produce a different number of units (e.g. 10,000 marbles).  The formula for time for units is:

T = X * (UP/NU)

where:

• T = Total time to process X units at the production rate
• UP = Time to process NU units
• NU = Number of Units for the production rate

Note: the production rate per unit is simply:

Prate = UP/NU

UNIT Production  Calculators

• Time for Units: Computes time to process a number of units.
• Units over Time: Computes number of units processed over a period of time.
• Total Cost of Units: Computes total cost based on the number of units and the cost of a single unit.
• Unit Cost:  Computes the Average Unit Cost.
• Variable Cost Rate: Variable cost of units including labor and materials.
• Variable Cost per Unit: Variable cost of units over two periods.
• Sell-Through Rate: Ratio of units sold verse received.

Production Calculator

The Production Calculator computes the cost in time or capital to buy, produce or consume commodities measured by number of units or by length, area, volume or weight.  It provides automatic conversions between different units for time, length, area, volume, mass and up to date currency conversions between several international currencies.
