| Mulch Calculator: | converts volume of mulch to/from the area to be mulched & depth of the mulch layer |
| Slope Calculator: | converts % slope to/from distance & change in elevation |
| Spacing Calculator: | converts number of plants to/from area to be planted & on center spacing required |
| Gravel Calculator: | converts volume of gravel to/from weight |
Global Settings & Options
| Units: | Selects the default units for all calculators: metric or feet & inches. |
| Precision: | Selects how many decimal places are displayed. Calculations are performed to full precision then rounded off to the selected number of decimal places. |
| ShowInput: | Displays the input to each field in the selected units |
| ShowMath: | Displays the math for the calculation |
The Slope Calculator uses the formula:
Slope = Rise / Run
Where:
| Rise | = | change in elevation |
|---|---|---|
| Run | = | distance over which the change in elevation occurs |
| Slope | = | ratio of Rise to Run (may be expressed as a percent) |
Enter values into any two fields to calculate the third. Input can be in the form 2'3", 3m, 5yd, 3%, etc. If no units are entered the field units are used. Calculated results are shown in blue.
Slope input values of 0.4 and above are assumed to be a percent slope. Slope input values less than .4 are assumed to be the ratio of rise to run. Enter a % to force a value under 0.4 to be treated as a percent, (eg 0.4%) .
Click the padlocks to lock and unlock each field. A locked field will not be recalculated, but will accept input. Up to two fields may to be locked at a time.
The Mulch Calculator uses the formula:
Volume = Area * Depth
Where:
| Volume | = | number of cubic yards (or meters) of mulch |
|---|---|---|
| Area | = | number of sq ft (or meters) to mulch |
| Depth | = | thickness of the mulch layer |
Enter values into any two fields to calculate the third. Input can be in the form 3cu m, 25sf, 4", 10cm, etc. If no units are entered the field units are assumed. Calculated results are shown in blue.
Area and Volume fields allow you to enter the dimensions of the area or volume. Input must begin with the letter D, followed by each dimension separated by an x. For example: d 10ft x 25yd x 3ft. If the units are omitted feet (or meters) are assumed.
Click the padlocks to lock and unlock each field. A locked field will not be recalculated, but will accept input. Up to two fields may to be locked at a time.
The Plant Spacing Calculator uses the formula:
# Plants = Area/Spacing2
Where:
| # Plants | = | number of plants required |
|---|---|---|
| Area | = | number of sq ft (or meters) to be planted |
| Spacing | = | distance between plants |
Enter values into any two fields to calculate the third. Input can be in the form 15sf, 3m2, 18", 30cm, etc. If no units are entered the field units are assumed. Calculated results are shown in blue.
The Area field allows you to enter the dimensions of the space. Input must begin with the letter D, followed by each dimension separated by an x. For example: d 10yd x 6ft. If the units are omitted feet (or meters) are assumed.
Click the padlocks to lock and unlock each field. A locked field will not be recalculated, but will accept input. Up to two fields may to be locked at a time.
The Gravel Calculator uses the formula:
Volume = Weight * CF
Where:
| Volume | = | number of cubic yards (or meters) of gravel |
|---|---|---|
| Weight | = | how much the gravel weighs |
| CF | = | a conversion factor, its value depends on the gravel type |
Enter a value into either the volume or the weight field to calculate the other. Input can be in the form 2cu yd, 12m3, 5tons, etc. In this mode, if units are omitted feet (or meters) are assumed. Calculated results are shown in blue.
The Volume field allows you to enter the dimensions of the volume. Input must begin with the letter D, followed by each dimension separated by an x. For example: d 1yd x 54sf. If the units are omitted feet (or meters) are assumed.
Use the Type box to choose the description that best matches the characteristics of your gravel. Select 'Rule of Thumb' to use a generic conversion factor of 1.5 tons per cubic yard (1.78 tonnes per cubic meter).
The conversion factor values are derived from the Reade Advanced Materials weight per cubic foot table. http://www.reade.com/Particle_Briefings/spec_gra2.html
