About Cubic yard (in³)
A cubic yard (yd³) is the volume of a cube with 1-yard sides (3 feet), equal to approximately 764.6 liters or 27 cubic feet. It is the standard unit for ordering concrete, topsoil, mulch, and gravel in the United States. Ready-mix concrete trucks carry 8–11 yd³ per load. A typical house driveway requires 3–5 yd³ of concrete. Landfill capacity and solid waste volume are also measured in cubic yards.
A standard concrete mixer truck carries 8–10 yd³. A garden mulch or topsoil project might require 1–5 yd³.
About Imperial teaspoon (imp tsp)
The imperial teaspoon is a unit of volume equal to approximately 5.919 milliliters, one third of an imperial tablespoon. It is larger than the US teaspoon (4.929 mL) and the metric teaspoon (5 mL). It appears in pre-metrication British and Commonwealth recipes. In medicine and pharmacology, both the UK and US have standardized on the 5 mL metric teaspoon for dosing, replacing all customary teaspoon sizes. Modern UK recipes do not use the imperial teaspoon.
Pre-metrication British recipes called for teaspoons of approximately 5.92 mL. A standard UK medicine teaspoon is now 5 mL (metric).
Cubic yard – Frequently Asked Questions
How many cubic feet are in a cubic yard?
One cubic yard equals exactly 27 cubic feet (since 1 yard = 3 feet, and 3³ = 27). It also equals approximately 764.6 liters.
Why is concrete measured in cubic yards?
The US construction industry uses cubic yards for ordering concrete as the traditional imperial bulk material unit. A standard ready-mix truck carries 8–10 cubic yards per load, priced typically at $100–$150/yd³.
How much does a cubic yard weigh?
Weight varies by material. Concrete weighs roughly 2 tonnes/yd³ (≈ 4,050 lb). Dry soil is about 1.1 tonnes/yd³. Mulch is about 0.4 tonnes/yd³. Gravel is about 1.4 tonnes/yd³.
How many cubic yards of concrete does a driveway need?
A typical two-car driveway (20 × 20 ft) at 4-inch thickness requires approximately 5 cubic yards of concrete. At 6-inch thickness, about 7.5 cubic yards.
How do I convert cubic yards to liters?
One cubic yard equals approximately 764.6 liters. Multiply yd³ by 764.6. For example, 5 yd³ = 5 × 764.6 = 3,823 liters.
Imperial teaspoon – Frequently Asked Questions
How many milliliters is an imperial teaspoon?
One imperial teaspoon equals approximately 5.919 mL — slightly larger than the US teaspoon (4.929 mL) and the metric teaspoon (5 mL).
What is the difference between an imperial and a metric teaspoon?
An imperial teaspoon is approximately 5.92 mL; a metric teaspoon is exactly 5 mL. The metric teaspoon is now standard in UK cooking, medicine, and pharmacology.
Is the imperial teaspoon used today?
The imperial teaspoon is obsolete in modern UK, Australian, and Canadian cooking, which all use the 5 mL metric teaspoon. It may appear in cookbooks published before the 1970s metrication period.
Why is a "pinch" of salt not as vague as it sounds?
A culinary pinch — the amount you can hold between thumb and forefinger — is roughly 0.3–0.5 mL, or about 1/16 of a teaspoon. Professional recipe developers have measured this and found surprising consistency across people: the human fingertip geometry constrains how much fine powder you can grip. A "dash" (liquid) is about 0.6 mL, and a "smidgen" is half a pinch (~0.15 mL). These folksy terms survive in recipes because they map to real, repeatable volumes — within the tolerance that salt and spice measurements actually require.
Why did the UK standardize on 5 mL for medicine teaspoons?
The WHO recommended the 5 mL metric teaspoon for medication dosing in the 1970s to eliminate ambiguity between imperial (5.92 mL), US (4.93 mL), and other teaspoon sizes. A calibrated 5 mL oral syringe is now the recommended tool for all liquid medicines.
